unixnewbie:
SATA disks appear with the /dev/s??? syntax because it was convinient to reuse some of the same SCSI machinery to present an interface to the disk to programs (see http://kerneltrap.org/node/5549 for details). It's not really emulation rather it's just naming. Rumour has it in a future kernel PATA devices will use this same libata interface that SATA disks use now and at that point they will turn into /dev/s??? nodes too.

Your particular SATA interface is VIA based so it would not be impacted by this 2.6.20-16 change (which I believe affects some unknown subset of Intel ICH[456] interfaces). Thanks for tending the forums - I do check by that thread from time to time but there's a lot to read so I only actively follow the links to posts that Lars suggests.

I would be interested to hear from ICH6 owners who have the same device renaming as Andrew and _especially_ interested to see the
lspci -vvv
lspci -vvvn
cat /proc/interupts (for 2.6.20-15)
cat /proc/interupts (for 2.6.20-16)
for Intel ICH[456] users who have IRQ problems that weren't present in 2.6.20-15.
