I just booted 2.6.21.1 (the latest AFAIK) from my /dev/sda, which is a SATA
drive. If it is sda*, it is the SCSI subsystem, otherwise it would be hda*.
% dmesg|grep sda
SCSI device sda: 156250000 512-byte hdwr sectors (80000 MB)
sda: Write Protect is off
sda: Mode Sense: 00 3a 00 00
SCSI device sda: write cache: enabled, read cache: enabled, doesn't support
DPO or FUA

So once again: if it is SATA, you need (in addition to the driver for your
SATA chip):
CONFIG_SCSI=y
CONFIG_BLK_DEV_SD=y
and, eventually
CONFIG_BLK_DEV_SR=m
And btw, even PATA is in the SCSI subsystem nowadays (my system has SATA hd,
but PATA cdrom, attached to an Intel ICH6 chipset):
% dmesg|grep -i scsi
SCSI subsystem initialized
scsi0 : ata_piix
scsi1 : ata_piix
