also, in openfirmware, if i type "devalias hd", i see this (transcribed visually, i hope i didn't botch anything): /pci@f2000000/mac-io@17/ata-4@1f000/disk@0 So the mapping chosen looks right up until the last couple sections. in particular, .../scsi@0/sd@0,0 should be .../disk@0. note that this is a parallel ATA device, but it shows up as /dev/sda under a modern linux kernel due to the modern ata subsystem. perhaps something in grub thinks that /dev/sda must be scsi?
