Its basically the same software API but different hardware. But I would actually welcome a driver integration. If you would be willing to let me wedge the mmtimer specifics into the hpet.c driver ;-). I would insist though that the way mmtimer maps its timer to userspace be also supported by the hpet driver and that you will not insist on preserving the current memory layout of the userspace mapping for hpet. The rest of the API could be shared to large extend.
