Re: ACPI support on Compaq Presario 2500
(I hope you don't mind me stepping in Jörg i just had a related
problem here)
Jörg's tracking was straightforward so far, and i think he's
right to suggest a close look at the hardware at this point.

There's a newer BIOS available.
Since your dmesg contains ACPI errors, I would try to
upgrade the BIOS first before any further tracking.
There use to be instructions on the respective website (phoenix).
Usually it boils down to run a .exe from a windows, but there
are other approaches through different tools, also for linux.
Certainly this list has support if needed.

Should be a P 4-M. Admittedly i can't decide exactly, but i think you've
got quicker access to the exact specs than me.
Try to search /var/log/kern.log, since your dmesg was cut off.
It's important to know which speedstep module you should look
for.
It's still not always easy, for example if cpuid reports Pentium Pro, you have
to know that Pentium M was derived from the P-III Pro line (and not P4).

Hyperhtreading points to M-4, also 1024 K of L2 Cache
(though there's only 512 K installed it seems).

But i wonder why your attached dmesg doesn't mention power states.
Maybe that was already expired. (dmesg is a ringbusffer with limited capacity).
--> less -p "thrott" /var/log/kern.log
I can see these messages here on a Pentium-M:
"Oct 6 16:55:03 lynx kernel: ACPI: Processor [CPU0] (supports 8 throttling states)"
The safe way to proceed would be, upgrade the BIOS, install a recent 2.6.18 kernel
source, get a proper .config file from the net, (any 2.6.xy should do), make oldconfig,
plus make menuconfig to adjust to your specific hardware (according to the manual
or windows system information), and try to set anything as modular as possible. except
access to the root filesystem, and other reasonable boot-up stuff. Compile without initrd
(man make-kpkg).
Then update your debian (Sid), and look if powernowd is runing.
