"OLD_XORG" causes an immediate hard lock with games/minetest (I wanted
to rule out mesa-demos as it seems to compile its own version of mesa vs
libGL?) I cannot SSH in or do anything except reboot. I assume you are
also running CURRENT. If that is the case, I think we can say works on
hardware (g5 agp) for certain, and it doesn't seem to work so far on the
one mdd g4 tested. I am upgrading to WITH_NEW_XORG again, because it got
further than an immediate hardlock in OLD_XORG for me. I did not install
xfce this time, just minetest and blackbox. I tried xorg-server with
AIGLX off as well as on too.

So possibilities:
Radeon 9000 has some hardware quirk
G4 MDD has some hardware quirk
My radeon 9000 is broken
My G4 MDD is broken
Remotely possible CPU=7450 or -O2 is breaking things?
