I was able to determine this issue appeared with acpi.c rev 1.159 and
related ("Add support to ACPI to manage its own resources."). Looking
at devinfo -vr before and after the commit (see below) seems to
confirm that something changed, although I can't understand how that
caused the breakage. In fact, all the involved I/O ports are not
reserved by any acpi_sysresource*, so I have no idea where to go
from here.

Nate (or anybody else), any idea?

Bye,
	Andrea
