for -current, just kldload cpufreq, or compile kernel with
device cpufreq
then you can configure powerd via /etc/rc.conf
for RELENG_5, specific low level drivers are not yet been MFC,
but the cpufreq infrastucture is.  So you have to do something
like that in the time beeing:
On, say, $HOME/cpufreq,

cvs co src/sys/dev/acpica/acpi_perf.c
cvs co -P src/sys/dev/cpufreq
cvs co -P src/sys/i386/cpufreq
cvs co -P src/usr.sbin/powerd
mkdir acpi_perf
cp src/sys/dev/acpica/acpi_perf.c acpi_perf
cp -r src/sys/i386/cpufreq .
cp src/sys/dev/cpufreq/ichss.c cpufreq
cp -r src/usr.sbin/powerd .

Then modify or add some Makefile:

I'm using the following:
cat Makefile
SUBDIR = acpi_perf cpufreq powerd

.include <bsd.subdir.mk>


cat acpi_perf/Makefile
CFLAGS+=        -I@/contrib/dev/acpica

KMOD=           acpi_perf
WARNS?=         2
SRCS=           acpi_perf.c
SRCS+=          acpi_if.h bus_if.h cpufreq_if.h device_if.h opt_acpi.h \
                pci_if.h

.include <bsd.kmod.mk>
cat cpufreq/Makefile 
KMOD=   cpufreq
SRCS=   est.c ichss.c p4tcc.c powernow.c
SRCS+=  bus_if.h cpufreq_if.h device_if.h

.include <bsd.kmod.mk>

I also have to modify a little the Makefile for powerd as such:
# $FreeBSD: src/usr.sbin/powerd/Makefile,v 1.2 2005/02/26 22:50:25 njl
# Exp $

PROG=   powerd
MAN=    powerd.8
WARNS?= 6

BINDIR= /usr/sbin

.include <bsd.prog.mk>


Then do a make followed by a make install.

You can then, in order:
kldload acpi_perf
kldload cpufreq

and launch powerd(8) with option '-v' for testing purpose.

Yes

Don't know.
