I tried the VFCT patch on a Mac Pro 1,1, and it gives me a kernel panic. I
can't really give any details on it because the screen output is garbled. The
previous patch with adding the video ROM to the kernel works, but without X
support.

Should the VFCT table show up in /sys/firmware/acpi/tables? If so, the Mac
doesn't support this method. Does anyone know what Darwin/OSX does to get the
ROM?
