That'd be great.  HP's bureaucracy makes it hard for me to borrow
machines.  If you could also turn on CONFIG_PNP_DEBUG_MESSAGES
and boot with "pnp.debug", we should get some clues about what _CRS
returns for all the ACPI devices.  Just attach the resulting dmesg
to the bugzilla (http://bugzilla.kernel.org/show_bug.cgi?id=14183).
