I couldn't find a separate HPET block in the patched QEMU BIOS, nor in
my BIOS, and found the only reference to it in the AML in my bios, too
(Opened up Phoenix BIOS Editor and grepped the disassembled files)..
appears the only reference to it is in the DSDT.

I was leaning towards that option as well.
Thanks for the input!
