** Description changed:

  After a boot, my system idles at system temp=29C, CPU temp=31C according
  to gkrellm. If I do a sleep then resume, the CPU temp stays above 36C at
  idle. All desktop effects are disabled.
+ 
+ I also tried an Ubuntu live CD 2010-04-27 and it does the same thing. My
+ methodology was: boot, modprobe it87a, install gkrellm, suspend & resume
+ and then CPU temperature goes up by several degrees at idle. I also
+ noticed that if I then do a hibernate & resume the CPU temperature goes
+ back to normal.
