Hi,
 
Perhaps you already checked for this but my uneducated guess on this is that it has to do with buggy ACPI. Check out http://gentoo-wiki.com/ACPI for example.

If I boot without ac and check the the cpuinfo it will say it is
running at full speed (1.8 Ghz).  It feels like 600 Mhz or slower from
some compile tests I have done.

If anyone has a suggestion I would love to hear it.
