Hardlock on Thinkpad T42 Radeon 9600 Mobile

I love this plugin, but unfortunately no matter what settings I adjust (tried getting new vid drivers, direct x, tweaking display/opengl/d3d settings, vsync...fullscreen/windowed)
it hardlocks (cant ctrl+alt+del) and i have to power down to re-start. This usually happens anywhere from 3-10 minutes after I start R4
Any suggestions?
