Okay, I guess I'm a bit thick.

I discovered the fact that tpctl allows one to control the CPU speed
on my 770Z, so when I go and run it, I got an error message very
similar to ones I'd recently seen on this list.

Unfortunately, I followed all the advice that seemed to apply to me,
and even upgraded from tpctl-0.8.8 to tpctl-1.0.0, but still the
error persists:

# tpctl -pma=high
tpctl: System error message is: No such device
tpctl: Can't open device file /dev/thinkpad with flags O_RDWR.  Exiting.
# ls -l /dev/thinkpad
crwxr-xr-x   1 root     root      10, 170 Jul 18  2000 /dev/thinkpad

Now I did see that the new version of tpctl uses /dev/thinkpad as a
directory, but reading the README for tpctl-3.0pre2 I have the impression
that pre 2.4 versions of Linux should not advance beyond using tpctl-1.0.

So I seem to be rather stuck, and welcome any and all advice.

	Bill -- well, most advice,

P.S. if you're curious as to why I want to override the battery saving
CPU speed, it's because the AC decector on my laptop doesn't work, so
even when plugged in, I get poor performance -- it's been broken for 6
months, and it just occured to me that this was happening (xine just isn't
doing well enough with my DVDs).
