Hi Luca,

Motherboard vendors usually provide tools for $(TheOtherOS) that can

it's possible to make the ACPI driver and the "raw" one play nice with
each other[1].

[1] Unless their solution is "poke at the hardware and hope that ACPI
doesn't blow up", that is.
Without the sources it's hard to tell. And all these applications are
vendor-specific, so if they indeed have ways to avoid conflicting
accesses between ACPI and the rest of the system, these ways are likely
to be vendor-specific as well, and not documented.

Either way, this means we need the support from hardware vendors to
solve this concurrent access problem, and unfortunately I doubt this
happens anytime soon :(
