I'm running an Athlon 1400, 2.4.17, Matrox g550, SB-16 'Vibra' clone.
(got it after giving up on the ac'97 audio) 1.5G RAM...

I've had almost *exactly* these problems with "Return to Wolfenstien" in the
last few days, and Quake III to a lesser extent (less as in less-frequent
lockups). X-lockup, looping sound.

I tweaked just about everything in the bios, agp speed, apperture size
(whadda's this do anyway), and various Enable/Disable things.  Not a single
thing helped.  I also tweaked the crap out of Wolfensiten (Essentially
a hacked version of Q3)  After many many tries, I eventually set the
texture detail to 'low low low' with a particular combination of other things.

That was it, it stopped locking up.

I don't see how you can use this information directly with xmame.xgl,
but it might give you some pointers.
Sorry this has become off-topic, but the hardware and problem is
uncannily matched to what I was having last night.

Personally I think it's an AGP/GART/DRI problem.
are you booting with the "mem=nopentium" option ?
