Looks like on some Acer Aspire 1s with older bioses, reboot via bios
fails.  It works on my machine, (with BIOS version 0.3310) but
not on some others (BIOS version 0.3309).

There's a log of problems at:

This patch adds a different callback to the reboot quirk table,
to allow rebooting via keybaord controller.
