Unfortunately, I don't have answers to any of these questions/problems.  In 
my case, Intel DSDT/SSDT mods are common in the Mac world, so I was able to
find a lot of resources.  I'm guessing the wrong value could damage something,
but can't speak from experience.  the PSS values dictate CPU voltages and 
Freqencies, which dictate heat generation, so it'd be logical that this 
could cause damage.  I'd suggest looking up AMD datasheets for the CPU and 
chipsets.
