If this is an intel chipset, it's capable as functioning as both. In  
order to ensure that it doesn't show up as hda, you need to not  
include any of the normal Parallel ATA stuff. Only enable the Serial  
ATA drivers. Then it should work as you expect. It will require a bit  
of magic, like you'll have to boot into hda2, build the kernel with  
all the good stuff, then install it, modify grub and reboot. I seem to  
recall that I had this problem with an intel laptop of mine running  
the ICH7 chipset.

I could be terribly wrong, but that's how I'd go about trying to fix this :)
