So, I've read many things about this and one of them was thread:
http://www.linux.org.uk/mailman/private/cpufreq/2004-June/003812.html
about "[PATCH] powernow-k7: Userspace PST for Athlon XP-M on desktop
boards".
I know that only FID of mobile CPUs can be changed on desktop board.
Personaly, I've modded my Barton to Mobile one but I had no time to try
changing FID in Linux. In Window$ all worked well.
BUT !!!
Today, I've read on Tom's Hardware that there IS way to change VID on
the fly. He says that "AMD keeps the corresponding utility under lock
and key for security reasons."
http://www.tomshardware.com/cpu/20041001/index.html
So, if AMD has that utility for Window$,
http://www.tomshardware.com/cpu/20041001/athlon-underclocking-06.html
I guess it's posible to make something similar for Linux
Or, maybe, Tom just wants to raise number of hits for his site? ;)

Without the motherboard hardware supporting VID changes, this tool does
nothing. This is also what the article says: "But the motherboard, too, must
fulfill requirements in handling a pseudo-mobile processor." So - with some
boards it may work, most board don't recognize (i.e. connect) the VID pins.
If somebody has a list of boards that do use the VID pins - that would be
great.

Same story:
[root@beta tnt]# modprobe powernow-k7 mycpuid=0x6a0 myfsbspeed=200
mymaxfid=0x00 mystartvid=0xb mynumpstates=5
myfids=0x00,0x0a,0x06,0x04,0x12 myvids=0x0b,0x0d,0x13,0x13,0x13
FATAL: Error inserting powernow_k7

[root@beta tnt]# modprobe powernow-k7 mycpuid=0x7a0 myfsbspeed=200
mymaxfid=0x00 mystartvid=0xb mynumpstates=5

I guess that my CPU can not be recognised because it's modded Barton. I
made it 'mobile' by connecting L5 bridge on it. But, in Window$
everything works fine and I'm able to change multiplier on the fly.
Maybe I just use wrong mycpuid, but I've tried 0x6a0 and 0x7a0... :(
Is there any way to force powernow to work without checking of CPU?

I'm no expert here, but you may find more info using
dmesg. Also should fsb be 100 instead of 200? If you
have /dev/cpuid support in your kernel, I think
cpuinfo will give you the cpuid (I think so anyway)
I should say that I couldnt get this to work either,
although others on the list certainly have :).
