Okay now I understand.  Thank you for taking the time to explain!  :-)

And when you disable HPET in the BIOS, what happens?

Sure, you're free to try CURRENT.  The ATA code on CURRENT was
modularised, and also a very large patch applied; I can't promise it
fixes your CD/DVD drive issues though.

I had problems getting CURRENT to see my PCI SATA Promise controller (it
wasn't appearing in pciconf -lv, nor dmesg), but I had no problems with
CURRENT seeing my ICH7 controller.  I also had other problems with
CURRENT which caused me to go back to RELENG_7.  CURRENT is undergoing
lots of changes right now, so I recommend subscribing to -current if you
plan on running it.

I personally haven't written any ATA patches, except for extending
atacontrol to support per-disk write cache enable/disable.  I think
you might be confusing me with Andrey V. Elsukov, who *has* written
lots of ATA stuff.
