Hello,

i had the same issue about fifo timeout. You certainly get a very random
refresh of your screen too if you activate dri. That is not a Xorg bug
but rather a radeonfb one. It comes from radeonfb_accel.c, if i remember
well. Just try and read the patch i send to the list (thread "radeonfb
doesn't work with an ati X800 pcie", file: radeon_accel.c.2.6.20.diff)
Also, you will certainly need all the xxx.c.2.6.20.diff as well. You
will find them in the april archive. If that doesn't help you can try
luca'sone + aty.patch (same thread) In that case you are integrating a
bunch of xorg code in radeonfb :). Luca's patch isn't compatible with
mine except when applied with aty.patch. I need it for my card,
otherwise it doesn't work. But it could be incompatible with your card.
Luca's patch still generates 2 *.rej file. You can install them manually
and very easily byreading the rej file.

If nothing works for you , you have certainly a legacy instead an atom
bios. In that case most of the patches won't help you except perhaps
radeon_accel . But keep trying.
I get finally my x800  working with them. xorg and radeonfb work now
together without a problem. Indeed, i don't have black screens or screen
corruptions any more and dri is now working ;)

Good luck.
