 Well this is sort-of expected as we do not yet have a driver for ACPI
 display devices.
 But if you have time and interest, boot with "-v" and "-x" (see
 boothowto(9)), press various hot and function keys, and if any output
 appears in dmesg, write the mappings down with a paper and pencil. That is,
 most of the hotkeys for wmihp(4) are still unknown, and this so-called "WMI"
 is pretty much undocumented, non-standardized, black magic.
 Some functionality may appear also in the envstat(8) output.
