--- Comment #53 from Benjamin Lee <ben@b1c1l1.com> ---
I can also confirm that Radeon KMS works on my MacBookPro8,2 with kernel
version 3.8-rc6 and EFI stub boot. I also needed to add a device section to my
xorg.conf.
I don't see any video BIOS in /dev/mem so I guess it is loading from ACPI
instead. Out of curiosity, I tried to load fglrx and it failed to find a valid
VBIOS so fglrx must not have the ACPI loading method.
