>Description:

Currently hpet(4) -- which, btw, also lacks a manual page -- attachs to
acpi0 based only the PNP/HID -information.  This however does not work on
some ACPI-based systems that expose the HPET information via a so-called
IA-PC High Precision Event Timer Table.

>How-To-Repeat:

Code and DSDT exploration.

>Fix:

Make it optionally attach also via information from the HPET table.

I know how this should be done. So I'll also deal with this (incl. the 
manual page) some day.
