Of course. As soon as I'm done moving and my hardware is usable again :)
Only committed them into xsrc right before packing up so others can 
review and play with them.

No. The sunffb driver is full of bugs and doesn't really work as it is 
in xorg 7.0. We have other fixes as well ( like redrawing the whole 
screen on unblank on old ffb1 boards because blanking too long seems to 
muck up VRAM content there ) which I didn't port over yet.
None of that is in any way specific to NetBSD, but nobody seems to test 
this driver anywhere, especially not in a 64bit environment. I get the 
feeling we're the only ones who have it anywhere near working properly 
;)

In the PCI code I guess? Yes, it's not really cleaned up yet. I just 
took over things from xsrc/xfree.
I have a hack that would eliminate accesses to /dev/pci, /dev/ttyE* and 
use /dev/fb* instead on sparc64 ( that's why machfb exposes a /dev/fb 
at all ), maybe I should commit that at some point as well - it allows 
to use as many heads as you can cram video controllers into the 
machine, I ran my U10 triple headed with a Creator, onboard mach64 and 
a PCI Matrox Millennium II ( using a generic fb-only 'driver' ). 
Impossible with current xsrc since it mmap()s everything through ttyE0 
which lets you access only the console fb.

Feel free to submit what you think can be submitted. There's more to 
port over, like the acceleration code for cg6 boards, the pnozz driver 
etc. and I have no real idea if i broke anything for other platforms.

Won't be able to do that for a few weeks - the machine with the source 
is packed up. The bug is in the address length field when calling 
bind(), should be trivial to fix.

Should be fine at least with 3.0 and newer ( I tested only on -current 
though ).

have fun
