I have been using an IDE disk to boot, and a SATA drive for a second 
disk since RH9, and my setup has worked fine.

Before libata, SATA drives were using the IDE drivers. With the 2.6

Until 2.6.7, my drive on a sil 3112 was detected as /dev/hde. With the 
upgrade to 2.6.7, that changed, and now the drive is detected as /dev/sda.
