Mark,
good that you remember my earlier emails. Yes I waited for 111b to try
again. So now:
- I tried with event-mode and poll-mode.
- With both configurations I checked after a fresh reboot with
kstat and powertop
- With event-mode (the default I guess) I can not see that the system
is doing any power management of the cpu. Both powertop and kstat are
showing 2001 Mhz cpu speed.
- I also tried during runtime to change between poll-mode and
event-mode with editing power.conf and pmconfig. But this didn't
changed anything.
- Yesterday I had a longer trip by train and played during that time
with dtrace, but also didn't got any probe-fire to change cpu-speeds.
See more below.

cpupm worked for me well with osol2008.11 and other nevada builds. We
always checked that with kstat -m cpu_info and also one was able to
hear this with the cpu fan noise.

Hmm. I can't believe that I am the only one who has that issue with my
Toshiba Tecra M9. If yes maybe there is something with my
configuration or installation/upgraded installation. That could be
checked if I do a complete new install, but I am hestating because
this is my every day work laptop and opensolaris do not yet supports
dual-boot fresh install systems. (My older osol-b108 install does
power-management)
