That is not his problem.  If you look closer at his dmesg you will see that
it detects both the PATA-controller part of ICH7 (as atapci0) and the
SATA-controller part (as atapci1.)  The detected disk is attached to atapci0
(as ata0-master.)  Besides the reported disk model (WD800BB) is a
PATA-model.  (http://www.wdc.com/en/products/products.asp?driveid=10)

So if there are any SATA-devices attached to the ICH7 then they are not
detected at all by FreeBSD.
