yeah - I noticed that as it didn't boot at all :-)

I used GENERIC plus this option.
Find attached the dmesg and sysctl parts.
I tried clockmod value 0 and 7 and the temperature didn't get lower
than 52,500degC in IDLE mode.

For what it's worth knowing it, I also did a few observations with
Windows XP, SpeedFan and PC Wizard 2007. It appears that when idling
those apps gives the following values:
- CPU Speed =3D 789,17 MHz
- Disk =3D 33=B0C
- CPU Temp / Temp1 =3D 52=B0C
- Core #1 =3D 52=B0C
- Core #2 =3D 50=B0C
- CPU activity when idling =3D between 3 and 5%...

'Not sure if it's good news NetBSD don't do better than Windows but
at least it does not do worse :-)

I'm gonna try to get such values on an older laptop to see if it has
something to do with hardware implementation...

Regards,
