It is not supported any more in the sense that it won't get updated but
afaik it is still supposed to run.
Last I tried it there (which is a long time ago...) at least it worked.
Never used devfs with 2.4 though. The oops indeed looks pretty "generic".

Maybe it doesn't disturb you when you've never used it with drm before,
but the mmio accel just visibly causes more artifacts when doing things 
like moving windows around :-).

I've tried the patch with my radeon 9000pro, and it does not work there 
neither. Issues are pretty similar, moving (3d) windows around leaves 
artifacts (and eventually even a gpu lockup), xawtv overlay still 
doesn't work, but on this setup I got the mouse pointer back at least.
