Playing around with the Mesa3D demos last night I had 3 similar lockups. The system is a PII-400 128MB RAM, 256MB swap on vanilla 2.4.3 (also did this on 2.4.2-ac18 as it happens). There's:
a) A similar lockup to described above, I caught my 'resetv2' (small util to just initialise a voodoo2 then exit cleanly, or so I thought) chewing up VM like it was going out of fashion. Shortly thereafter solid lockup, LEDs not working etc, although I think I forgot to try Alt-SysRq+R that time to see if the keyboard would come back to life.
b) Running a Mesa3D demo that uses threads was fine with 3 or 5, try it with 10, instant lockup, no magic sysrq, had to hit the reset button. So I'd assume some other issue with threads in 2.4.3/2.4.2-ac18
