FWIW I can boot Linux 2.6.28 (32bit only, the CPU probably does not do
64bit) on a Mac mini.

I load grub directly without rEFIt. The vesa framebuffer has wrong
colours and both imacfb and intelfb produce distorted image (or they
did with some 2.6.27 kernel at least).

However, X works with AGP and DRM with the alien coloured console
intact - it's possible to switch between X and the console without any
immediately visible additional problems.

The X driver works as nicely as it does on any other hardware, at
least I do not see any glitches.
