Ok.  I think then that aibs just needs updating for your machine perhaps.

This is due to the way new-bus works.  When you load a new ACPI driver (like 
acpi_aiboost), all ACPI devices that don't have a driver are re-probed (in 
case the new driver handles any of those devices).  This results in the extra 
HPET device being re-probed as well.
