Ok, will give them a try.

Well, not sure. Compared to the pegasos 1 situation, where nothing
showed up on the screen, except the hardware cursor, Things seem to work
out fine at first, and only certain operation make it happen. The gdm
prompt comes up, you can log in, then once logged in, you can open a
gnome-terminal, and even do some stuff. Once you try moving the window
though, it starts moving, but then quickly freezes. I believe there is
maybe more a problem with the CPU and the graphic chip being in disacord
over the size of the CP ring.
Come to think of it, i have three negative tries (Radeon 7000, 7200 and
9200SE) and one positive (Radeon 7500), or at least claimed such, the
glxgears numbers obtained with the Radeon 7500 where not all that high
(maybe 300 or so), but still higher than the software only numbers i
obtain on my box with Radeon 9200 SE.
Also, the Radeon 9200 SE has only 64bit memory interface. I don't know
about 7000 and 7200, but maybe this is also the case for them, while the
7500 could have 128bit memory interface ? Not sure, will investigate.

Wait a minute, i can send them to you. I also had logs of the of the
7500 and 7000, but had them in /tmp and rebooted my box yesterday :/.
Anyway, here are the three DRI enabled logs :
this one is while it is loading.
this one is ones loged in gnome, opened a terminal, and started
typing in it (ls only).
this one is after having moved the gnome-terminal and locking up
X. Hardware cursor still works. i first moved the gnome-terminal
a bit, and it worked, but i insisted and it locked up.
