no no no no no.  The kernel will enable the ability of the software to
use the hardware.  It's like loading a driver in Microsoftnese.  The
kernel support itself is trivial for the CPU.  The software may be a
different story.  ACPI is really just getting settled down (it's
really new to Linux).  The GUI software for it is legion because no
body really knows what's the best way to deal with it.  I prefer
KPowerSave, others like the (spartan) little gizmo that Kubuntu comes
with.  I can't stand not being able to find out what my CPU is
throttled at.  Others could care less.  It's all about choice.

BIOS has nothing to do with it either.  BIOS controls virtually no
run-time behavior whatsoever beyond booting.  It's all software.
Speedstepping is extremely good if your processor supports it.  It can
save a load of power and reduce heat by a appreciable amount.  When my
laptop ran Windows XP (without throttling) it was running so hot I
could have fried an egg on the underside of my laptop.  I switched to
Linux, which had CPU throttling.  It runs at room temperature unless
I'm running something CPU intensive at the time (read: I'm a
programmer, so CPU intensive usually constitutes finding the nth digit
of pi or the first ten digit prime number found in e.)

I know of no kernel mods.  Mine works just fine with none.  I
installed the powersave daemon 'cause it's the little guy which
controls the hardware using kernel-supplied mechanisms.  I installed
kpowersaved because I like KDE.

Okey dokey.
