The lmsensors package in etch seems to work perfectly w/o any downloads.
Actually, I checked it and it seems it has been updated with the mods
from tyan already.  So, as debian users, you're in luck as usual!

ripper:~$ sensors
smsc47b397-isa-0480
Adapter: ISA adapter
temp1:       +33C  <-- cpu1
temp2:       +33C  <-- cpu2
temp3:       +29C
temp4:      -128C
fan1:     1393 RPM  <-- cpu1 fan
fan2:     1348 RPM
fan3:     1357 RPM
fan4:     1428 RPM  <-- cpu2 fan

This is with 265s "basicall" idle.  The CPUs (temp1 and 2) get as high
as 43C when running for a while at 100%.  [This is the ideal machine
for compiling 800 java files several times a day ~:^) ]

If you're seeing anything higher, then you need to triple check your
fans and heat sink mounting.  They're probably not working right.

Cheers,
