This thread was mostly about the msrtool utility.

That said, the original driver should be improved to not use a
hard-coded I/O base for GPIO, but read the relevant setting.
That's an easy fix in the driver.

But there's another issue; the driver searches for a board name
string in the BIOS memory when trying to detect if it is really
running on an ALIX board. That heuristic is not very reliable when
using coreboot.

I haven't come up with a really good alternative.
