I'm starting to feel that we'd probably get a better EST support
to port from NetBSD for now than sticking with the current version,
since FreeBSD decided to rely on _PSS object in ACPI table to
retrieve voltage/frequency data for newer/yet-to-be documented
Pentium-M CPUs, and we haven't ported it yet and probably that'll take
longer than to port NetBSD version of EST driver.

So my question is: Thomas(and anybody else), can you try my untested
patch and see if it works for you? (untested because I don't have
access to any Pentium-M machines now)

$ cd /sys/dev/est
$ export MAKEOBJDIRPREFIX=$HOME/obj		(/bin/sh syntax)
$ setenv MAKEOBJDIRPREFIX $HOME/obj		(/bin/csh syntax)

$ fetch -o est.c http://les.ath.cx/DragonFly/netbsd-est.c
$ make cleandir; make cleandir
$ make obj && make depend && make
$ su
# make install
(make sure you don't have `est_load="YES"' line
in /boot/loader.conf or /etc/sysctl.conf now)

# shutdown now
# umount -a; mount -ur /
(so as your partitions won't get damaged on kernel panic)

Good luck.
