If you mean the XFree86 that comes with NetBSD then the answer is  
yes. Xorg's driver lacks a bunch of bugfixes and workarounds. It  
should basically work but you'll see minor or not so minor glitches  
depending on your ffb model. Also, nothing keeps you from using xorg  
client libraries with the XFree86 Xserver. Another problem is that I  
found a few more RGB vs. BGR bugs in XFree86 XAA's xrender support  
code, it assumes that the target drawable is always RGB which is  
obviously bogus on many Sun graphics boards. Easy to fix, I'll do it  
in the near future. No idea if this stuff is fixed in Xorg but given  
their focus on PCish hardware I doubt it.

Yes, if you find one that comes with Sun firmware. They sold a few  
ATI and 3Dlabs ones under their own name - the PGX32 is a Permedia2,  
the XVR-100 is a Radeon and the other PGXes are different mach64  
variants.

have fun
