Some hardware has a HPET, but it is not possible to enable it via the bios.
There are many possible reasons for this, including broken hardware and
lazy bios-coders. Hardware which is "known" to have a hidden HPET
allegedly includes Intel ICH3m/ICH4m and VIA VT8237.
(It runs on my ICH3m right now. No blue smoke yet.)
A patch to enable your *unsupported* HPET may or may not be available
somewhere down this tree:

Currently, there is no way to enable the VT8237 HPET.
