So I've been eying this machine for a while:
http://www.kingjim.co.jp/sp/portabook/xmc10/
Original price was a rediculous JPY 96,000 but it's dropped to a reasonable
JPY 20,000 (about USD 200) so I picked one up.
bsd.rd boots, but GENERIC / GENERIC.MP fail to parse the ACPI AML; it
needs the following diff to boot.
Perhaps someone more familiar with ACPI than I can pick this up and
actually do something useful with the ACPI_OPREG_GSB instead of just
skipping it.
