That doesn't necessarily mean it isn't using the PCI bus.
I'm not up on SATA chipsets (for all I know things are different now -
corrections welcome), but in the recent past nearly all onboard storage
adapters still used PCI to connect to the south bridge chipset. One
exception we had was a dual P3 Tualatin mobo with a ServerWorks chipset -
the onboard LSI SCSI adapter had a direct chipset connection.
Note I'm not saying it does use PCI (hey I'm a little out of date with
hardware), just that just because it is onboard don't automatically assume
it doesn't use the PCI bus
You'll need to look at your motherboard schematic to be sure.
