Ok, this works for both grub and grub-legacy, and Linux is happy as
well. But illumos won't mount the root fs. From the AHCI debug I see:
ahci: process_ncq_command: [0] NCQ transfer LBA from 0 to -1, drive max 62914559
ahci: process_ncq_command: [0] NCQ reading 0 sectors from LBA 0, tag 0
and this looks a bit suspicious.
