Unable to find root fs with libata only 2.6.18-mm3

I dont have scsi or ide/ata support compiled into my kernel, only the libata drivers, now that they're split out from the scsi tree. As far as I could see from the "help" dialog, this was a valid configuration. However, I can't load the root fs using any scsi device name or ide device name. eg, /dev/sda1, /dev/sdb1, /dev/sdc1, /dev/hda1 etc etc. I tried the LABEL=/ option in the boot args, which should work and that gave me nothing.

My question is, do I still need to compile in scsi disk/cdrom/generic support into my kernel to get libata devices to work or is there some other syntax i'm missing? Libata detects my drives, but as far as I could see, and it flies by too fast to read, no device nodes were assigned to them.

If you do need scsi support, why isn't that done automatically when you select your libata drivers? or at least a pointer in the "Help" dialog to tell you to enable that ?
