Current AMD chips DO support power/frequency scaling in OpenSolaris. I understand that the older chips are not supported from reading around here.
The current support for PowerNow! is limited to those in the 10h family
and later.
I /believe/ this mean the Sempron M1, Phenom, Phenom II, and Athlon II
series of desktop processors, and the Barcelona and later Opteron
series, plus the Turion II notebook CPUs. I'm not so sure about the
Athlon X4 and the Santa Rosa series of dual-core Opterons (i'm pretty
sure they're 0Fh).
I finally found the completed lists for the 10h and 11h families:

I'm not sure of the blocking issues, but it certainly would be nice to
have PowerNow! supported through all the Socket F/AM2/AM2+ CPU families
(I can see ignoring all the DDR1-era CPUs, as they're at least 4 years
out of date now).
9) If you have more than one physical box, forget
sharing one keyboard, mouse and video with a KVM
switch, or even forget disconnetting the PS2 mouse by
mistake! If you do, you will loose control of the
mouse until next REBOOT! (This is GROSS isn't it?)
I use a USB KVM and it works fine with OpenSolaris. I switch around and it
doesn't cause any issues. I agree that it's irritating that it doesn't work
with PS/2 though, but PS/2 wasn't designed for hot-plug. Most PS/2 KVMs I've
used make the attached computer think the mouse and keyboard are still there at
all times.
Removing and reattaching PS/2 peripherals on ANY OS is a crapshoot.
PS/2 simply isn't designed to allow for reliable hot swapping. Good
PS/2 KVMs have little chips inside which emulate a constantly-connected
PS/2 device, which is why they work reliably - crappy KVMs are just
mechanical switches, which are the equivalent to plugging and unplugging
the PS/2 port (that is, take your chances). I've had no more
difficulties with OpenSolaris and PS/2 than I have with Linux or Windows.
USB does support hot-swapping, which I've found works nicely on pretty
much all OSes, with no real issues.
