I'll tell you how I did mine.  Just build all the sensor drivers into 
the kernel, not modules but built in.  Compile and boot the kernel.  
Methos one, if you open gkrellm and it can see the fans, temp and such, 
then it is working.  Sometimes you can look in gkrellm's configuration 
and find the driver.  When you open the sensors window, it will list the 
path which contains the name of the sensor.  Another way, cat 
/sys/devices/platform/ then hit tab twice.  Mine for example lists 
it87.552.  The it87 part is what you look for in the kernel.  If you 
want to be certain it sees everything, continue with the cat command and 
hitting tab until you get to where it lists all the fan and temp files.  
Mine has two temps and about 4 fans I think it is.  If you see what 
should be there then you have the right one.

Then go back to the kernel and remove everything but the one that 
matches what you found either in gkrellm or the cat command.  Rebuild 
the kernel and reboot.

This seems like a lot of trouble but after spending about two hours on 
google and not finding the info, that was what I did.  It isn't always 
the easy way but it works for me.

You could also google for "linux compatible hardware" and see if someone 
was nice enough to post what they used on one of those sites.  That 
doesn't always work.

Hope that helps or gives you a good chuckle for the round about way of 
doing it.  lol
