I updated to 6.0-CURRENT to test out the powernow
drivers on my machine. It's a laptop and the processor
is AMD Athlon-xpm.

I cannot be certain that I'm setting this thing up
right; and it may not even work on this box but I
suspect it does from that I've seen in this list. I'm
not sure how to check my cpu frequency. Any pointers
will be appreciated.

added to kernel:
device          cpufreq

added to rc.conf:

carmen# sysctl dev.cpu
dev.cpu.0.%driver: cpu
dev.cpu.0.%parent: legacy0

carmen# dmesg
CPU: AMD Athlon(tm) XP Processor 3000+ (1595.89-MHz

exciting surprises around every corner (241).
