Another CPU slows to a crawl after resume from suspend

Hi All,

Akin to previous messages sent some time ago to this list, my computer
becomes incredibly slow after a suspend-resume cycle.  I suspect that
what's happening is the CPU speed is being set to slow while suspended, and
that value never gets restored to the original tear-em-up frequency.

My laptop is a Hewlett Packard Omnibook Sojourn (equivalent to the
Mitsubishi Pedion), running RedHat Linux 2.2.10, with the 2.2.10 APMD
kernel patches and APMD 3.0beta9.

While it would be cool to have the bug figured out and fixed, since the
number of these machines is pretty small and it's probably some oddity in
the BIOS (6.0.I for those who care), I'm guessing it's more likely that,
somewhere, someone's written a little utility which allows the user to
switch between slow and fast CPU modes from the Linux command line.  Given
such a utility, the obvious workaround (okay, kludge) would be to insert a
call to this hypothetical set-cpu-speed-fast command in the APMD resume
script.

Anyone have such a thing?  Or better ideas?  

Cheers,

	- pz.
