Have some of the _T_0 optimus calls working although still having difficulty
with ROM transfer see below,any suggestions ?.
Used kernel 2.6.36 which has some new tracing for acpi and further intel
improvements.
I have built a single nvidia kernel module based on the new nvidia drivers 2.60
see nvidia site ,seems they are continuing with the linux development ?.

Stopped cpufreqd from throttling on open loop ,close loop control of cpu
executed ,increase in GL fps to 1980 fps .
ldd /usr/bin/glxgears indicates that the mesa library is used ,no nvidia
glx libraries installed at present .
Cheers
