One final thought -- your DSDT doesn't provide any power methods
such as _PS[0-3] (I grepped your DSDT so basing my statement on
more than just the output above), and without those, I'm pretty
sure that there's no way for the OS to communicate to the BIOS
that we want to power those slots on.
So, something funky is going on with your BIOS. This isn't some
weird proto board or something, is it? ;)
