Ok,

Nearing completion of this tale I think..

Turns out there is a known problem with psmouse, which leaves the
system / ACPI / something in a bad state if psmouse is loaded before
shutdown or reboot. Googling tells me that either removing batteries, AC
etc.. before powering up, booting Windows, or shutting down Linux with
psmouse removed, will "fix" the symptoms.

Magic...

Removing psmouse before boot from the init scripts, I reboot (no
ec_intr=0), and not only does the battery status work properly, the CPU
frequency scaling also works up to the CPU's maximum 2Ghz (which it
never did before, it only ever reached 1.6Ghz).

I'm now inclined to wonder if the F.08 BIOS might have worked ok, and
provided the appropriate SSDT for CPU speed control, had the psmouse
module been removed before reboot.

Unless anyone is keen to know the results, I'm not that motivated to
find out (by upgrading the bios again), as I'm not keen to either wear
out the bios flash chip, or have a random corruption during an update.

Thanks for all the help so far,

Regards
