take a look.
it is almost the same prob
also you may know how to do a kernel rebuild but you may learn some things from this person >>>
and yes the SATA drives are not pri or sec they are however recognized first as hde & hdg then when mounted they are sda and sdb. They do use much the same way of recognition from what I gather as SCSI do.
I have been trying to use Mandrake 10.0 with kernel 2.6.3 with also two others 2.6.7 and 2.6.8.
there is support in both of those but as of yet I am unsuccessfull to boot from my SATA 160GB HDs.
I have the same SATA driver chip on a ASUS P4S800D-E Deluxe MB. It has 4 sata ports and Gb ethernet built-in.
if you strike big and find a way to boot your box with the SATA drives, please drop me a line.
