Great, one more bug bites the dust. On the first I had picked
up the incorrect keyword somewhere ("depth" instead of "cmode"),
and had been using it from day one. On 2.2 it was ignored and
the display left at 8bpp, in 2.4 it now causes init to leave
the display in a strange state. If that doesn't help you
find it, I'll dig into the code in a couple of days. With cmode
all is fine.

Is there any hope that the ATI 128 DRI stuff is going to
get reenabled soon?
