Like Henrique wrote, the powermanagement solves the hot palmrest issue
for me. It still gets warm, but temperature is acceptable for me.
On my thinkpad there is also the fingerprint reader on the right hand
side of the palmrest. A couple of months ago there was some bug which
would make it heat up. I solved that by enabling usb powermanagement.

The fundamental theorem of algebra is open source. Like any other
mathematical theorem it can be applied free of charge and everybody
has access to its proof and can convince himself how it works. Why
should software be any different?
