Ah, great!  In that case, can you boot with "nomodeset 3" so you're at a VGA
text console and get some VBIOS traces for me?  Instructions on grabbing
vbtracetool are at http://nouveau.freedesktop.org/wiki/DumpingVideoBios

I'll need:
./vbtracetool -2 2>vbios.rom
./vbtracetool -lp 2>post.iolog
./vbtracetool -dp 2>post.log (this will possibly take several minutes to
complete)

If you could "bzip -9" those, and mail to mmio.dumps at gmail.com I'll take a look
when I get a chance and see if I can find the missing magic.
