Also, this mobile GPU has 512MB VRAM so I'm not sure I understand it reporting 256MB only?
I am able to still to reboot the machine but it never finishes the booting sequence it just hangs on firmware loading. This is 2.6.32-rc6 git master from Today November 6th, 2009 @ 12AM

I doubt it's hanging on that. > Also, this mobile GPU has 512MB VRAM so I'm not sure I understand it reporting > 256MB only? > We don't currently support vram larger than the max PCI BAR size (256 MB). That's slated for a future ttm enhancement.

Close it. This is Debian's issue. Fixed ramdisk tools and this now works. r6xx also is not locking up either with KMS enabled.
