Yeah, we support it now.
Turned out genfb would have worked out fo the box if the firmware wasn't buggy - the OpenFirmware calls to change palette registers don't work and in 32bit colour the 'linebytes' property incorrectly contains the same value as 'width'. So I added a workaround, if 'linebytes' is smaller than bytes_per_pixel*width then we know 'linebytes' is bogus and use that instead. Yeah, it's slow but it works.
The PGX32 isn't much more than an off-the-shelf Permedia2 with Sun firmware and a few jumpers to turn off things like fixed VGA PCI resources. XFree86's glint driver supports the chip and would have worked out of the box if it had ever been tested on a big endian machine with an operating system that enforces PCI mapping restrictions - NetBSD doesn't allow you to mmap PCI space that doesn't belong to any device. The driver on the other hand was written a little bit sloppy - there's a register block, 128kB, which contains the same set of registers twice, once big endian and once little endian. The little endian block comes first. Now the problem is that the driver always tries to mmap 128kB even when it wants the 2nd part which results in attempting to map 64kB of unoccupied PCI space. Trivial to fix but still annoying.
Other than that it Just Works(tm).

So 3.0 is about to be released Really Soon Now(tm) - why should anyone care? Here's why:

First, the infamous sleep forever bug that made various UltraSPARC boxes lock up randomly has been fixed. Finally.
Second, NetBSD/sparc64 switched to the wscons console driver which allows nice things like virtual consoles, different terminal emulations, fonts and so on. We have accelerated drivers for most Sun-labeled graphics devices you're likely to find an any supported Ultra, namely the CG6 family ( GX, GX+, TGX, TGX+ ), ffb ( Creator, Creator3D ), afb ( Elite3D ) and mach64 ( PGX24, graphics chips found on Ultra 5 and Ultra 10 mainboards, probably others )
With 3.0 can also run XFree86 on all of these, with full acceleration. The acceleration part for the cg6-driver had to be written from scratch and there were a few bugs to squish in the ffb/afb driver and the Xserver itself but now things work nicely.
To sum it up - we're almost on par with i386 feature-wise now. For 4.0 I'll hopfully omit 'almost'

The cg6 isn't exclusively found in sparc64 machines, there are probably more 32bit Suns equipped with this kind of graphics board and of course both the console and the XFree driver work there too. However, since we still don't have wscons-compliant console drivers for all framebuffers commonly found in 32bit Suns these won't be included with 3.0

What's to come after 3.0:

• A new ffb driver that uses XAA and supports hardware-accelerated alpha-blending ( this greatly speeds up drawing of anti-aliased text ) - works in -current, too new for 3.0.
  
• support for switching virtual consoles with X running. Still needs some bugs fixed.
  
• wscons and XFree on NetBSD/sparc. Right now we have drivers for Weitek P9100 and CG6 ( both X and console ), cg14 and ZX/leo are being worked on.
  
• greatly improved support for Tadpole SPARCbook 3GX and similar laptops. We have drivers for the audio chip ( still somewhat experimental but good enough to play MP3s ), PCMCIA ( stable ), console (stable, but not active since NetBSD/sparc didn't switch to wscons yet ), XFree86 ( currently 8bit only but with some acceleration ), CPU power saving, more feedback on the built-in status-LCD and so on.
  
• XFree86 now works on the JavaStation Krups. Unaccelerated and 8bit only but at least it uses a hardware cursor, it's definitely usable for light work ( and you won't run anything heavy on a 100MHz MicroSPARC IIep anyway )
