it should NOT do this. I set the bios to disable speedstep and to
'max performance' while on AC. also, i run apm and not acpi.

that was also one of my suspicions. the fan is brand new, ibm replaced
it after i sent the unit in because of heat problems.
could it be that the design of this laptop is bad, when it comes to
shouldn't i get the full 1.8GHz when running on AC, and be able to
do a buildworld without any sig11 on a hot summer day (~28 deg c room
temp). those sig11 are just another thing that may be connected to my
low cpu freq...
