Just checked what u propsed, and it works.
So, i'm pretty sure, that the problem is with the ASL code. I thought
of an implementaion change of the ASL code, which will make it work:
we will change it from:
if ( slt == 0x1 )
else if (slt == 0x2)
else if (slt == 0x20)

to the following (just as an example):
if ( slt < 0x10 )
    if (slt == 0x1)
} else {
    if ( slt == 0x11)

What do u think about this?
