[ltp] ATTENTION T40/41/4*p OWNERS!

[Justin Lintz]

Slightly off subject but how long of a battery life are you getting with
your t40p and cpufreq?  I am currently getting around 4:30 with a full
charge, brightness down and wireless off, atleast that's what apm tells me.
In windows I get close to 7 hours.  I have the 9 cell extended battery.

	If your system doesn't have cpudyn or cpufreq and you boot on AC, 
your CPU will be at full speed forever.  Perhaps this accounts for the fan 
being on all the time (and rotten battery life too).  When I activated 
cpufreqd in SuSE 9, the battery life on my T40p, well, perhaps didn't 
double, but certainly improved significantly.  At the moment, writing 
e-mail, the CPU is at 600MHz and the fan is, if not completely off, at 
least at a very low speed with no significant noise.  If I kick off a 
compile, it shoots up in MHz and the fan noise kicks in pretty quickly.
