Hi,
with b111a now I can boot again my Toshiba M9.
1.I discoverred that Power Management seems no longer to work.
(The fan is blowing like hell and "kstat -m cpu_info" shows in

New Bug with b111a ?
<snip>
The current_clock_Hz is a little deceiving. The Power Aware
Dispatcher results in much more frequent P-State transitions. Try
running /usr/bin/powertop for better information.

Indeed. powertop shows the system switching nicely between 800Mhz
and 1401 Mhz), with most time spent at 800. Thanks.

Unfortunately, I don't see the same thing on my Tecra M10. Perhaps I
haven't twiddled the right switch to turn power management on, but I
would've expected this to have been on by default. In any case,
powertop reports that my machine's always at 2531 Mhz (more detailed
output below in case that helps).

Could you provide the contents of /etc/power.conf as well? Thanks!
