Good to hear that my patch actually makes more than cosmetic difference
for somebody.  My system doesn't hang even with the stack trace.  

I posted another patch on the bug page.  It widens the BOOTFB resource
to match the PCI BAR instead of making it busy. With the new patch,
nvidiafb doesn't report that the resource is busy, it reports
unsupported hardware, which is true.

Old patch:
nvidiafb 0000:01:00.0: BAR 3: can't reserve [mem 0xf0000000-0xf1ffffff
64bit pref]
nvidiafb: cannot request PCI regions

New patch:
nvidiafb: Device ID: 10de0ffc
nvidiafb: unknown NV_ARCH

I'll send the patch to x86 at kernel.org, it's clearly not an nvidia issue.
