The information I've had up to now is that KMS works well on x86 (if you
have firmware installed) and fails on many PowerPC systems. I simply
had no information about any other platform, and I tend to assume that
if a feature is primarily used on x86 and is broken on another
architecture that it is broken on more of them.
But I think a lot of the problems with radeon on PowerPC are specific to
the on-board Radeon chips in Mac systems which have odd firmware (no
ATOM-BIOS). This presumably doesn't apply to any other architecture,
and so only PowerPC should get the special treatment. Right?
Yes, that's correct.
