apm & keyboard

[B0Ti <9915104t@example.com>]

Hi,

I've recently upgraded my system, and got this new keyboard that has
sleep, wake up and power buttons on it. I'd like to make it work under
Linux.
If I press either of these on the console, my kernel reports: "keyboard:
unkown scancode xxxx". Under X, nothing happens, xev doesn't say
anything.
I have read the relevant howtos, got apm support in the kernel, and
played around with loadkeys, setkeycodes, apmsleep, apmd, etc, but still
couldn't figure out a way to make these work together.
Any help would be appreciated.

Second question. Little bit offtopic, sorry.
I have got an AMD Athlon 800, and it gets kinda hot when it gets
something to work on, though I bought a huge heatsink for it.  Not a
long ago I overclocked the FSB, so now it's running at 572mhz and the
CPU temperature, according to the temperature sensor, rises up to about
56 deg C under 100% CPU usage, which is around 5 deg C higher than it
was before when it ran at 800mhz.
>From what temperature limits is it "unhealthy" for a processor to run?

thanks,
B0Ti.
