I'm on a Mac Pro 1,1 with the original ATI X1900XT card, and had similar
problems booting via EFI. After the modesetting was initialized the screen went
blank, but the computer completed booting.
Therefore, I applied the patch, which made the kernel boot absolutely fine.
When I want to start X however, the picture gets distorted. No errors or
warnings are shown in the Xorg log file. Starting X with BIOS boot works
absolutely fine with the same install.
One thing I've no noticed is that the kernel doesn't reserve the memory space
for the video ROM (0x000c0000-0x000cffff) in EFI boot as it does in BIOS mode.
I've tried to write a DSDT patch for this to reserve the area, without success.
I suspect that the ATI drivers (xf86-video-ati) tries to read the video ROM
both from the kernel, that was placed there through the patch, and from the
memory range, which is not there in EFI boot.
I run a Gentoo install with Grub2 boot, 3.3 vanilla kernel, Xorg-server 1.12
and xf86-video-ati compiled from GIT.
