BTW, i just ran JACK realtime on a T41p with the firegl T2 128MB, using the ati 3.7.0 drivers on a 2.4.22 PE/LL kernel with no problems. Alsa 0.9.8 using the builtin audio (snd-intel8x0). the machine itself has 512MB of RAM.
I tested with alsaplayer, jack-rack and freqtweak together loading the system to > 80% cpu utilization and no xruns at 256 period size (and possibly less) and 48k. And yes, ATI's drivers have DRI enabled.... note that i didn't try to run any opengl accelerated apps at the same time as jack yet..... but i don't see any of the problems with regard to memory locking. maybe 512 is too much RAM to notice the problem. jlc
