I've started looking into the DSDT to fix various methods, so far just
tried to figure out what all methods do.

In the mean time I upgraded to kernel 2.6.15-rc4 and most problems
disappeared. Still using the original DSDT. During heavy usage cpu
temperature rises to 76-78, and never reaches 80.

Yesterday I upgraded to kernel 2.6.15-rc5, and during compilation of
ndiswrapper, while browsing the internet, it shutdown. If I compile
ndiswrapper and don't do anything else, the cpu temp touches 80
briefly, but does not shutdown. Under -rc4 this does not happen.
