I later noticed that ACPI functions (lid, hot keys etc.) were effectively
disabled by that bug – acpi_listen reported nothing at all.

With the patch, those ACPI errors are gone and the ACPI functions work again.
I see no other significant differences, but output is attached regardless
along with an ACPI dump. (rt2860sta is also present.)

(This leaves only the I/O resource conflict; but, unlike this, that's also
present in 2.6.27, doesn't seem to cause any harm, and looks like it's
specific to BIOS rev. 1603 and possibly others > 1301.)
