On this note, here's how I am currently getting this info from the 
server I am working on (at present only fan speed data);

lsmod
Module                  Size  Used by
smsc47m1                8836  0
i2c_isa                 4352  1 smsc47m1
i2c_dev                 8452  0
i2c_core               18688  3 smsc47m1,i2c_isa,i2c_dev
e100                   33540  0

under 2.6 kernels, one can compile i2c support as a module, load the module;

i2c_core

then run sensors-detect to try and find out what chip you have (unless 
you want to open your computer and do a visual inventory).  In this 
case, loading the smsc47m1 module calls the other modules.

Then running "sensors" gives this output.  The same can be done for 
temperature.

sensors
smsc47m1-isa-0800
Adapter: ISA adapter
fan1:     8192 RPM  (min =  640 RPM, div = 8)
fan2:     10240 RPM  (min =  640 RPM, div = 8)

Then it's a matter of running a script to send email if RPM is < or 
equal to a certain value. If there's interest, I'll post that when I've 
got it written.
