Newer versions (Asus G1s , etc) use updated chipsets. But the "original" 
is i945 based.

Oh, i see..
It is kind of expensive (considering i have to ship to my country). 
Well.. if i need to get it, ill consider it. Meanwhile, rebooting is not 
that awful.

I'll get the tools, and try again when they arrive. I'll keep the list 
posted ;)

If more ideas come up, that will be good too.
