Oops.  I through it does, but seems this is only the case for the old &
deprecated boot=on (and maybe even that only in qemu-kvm).

It's two only:
  -drive if=none,id=<name>,...
  -device virtio-blk-pci,drive=<name>

I think you can't.

seabios uses a few numbers just above 100 for the internal default
ordering (hd first, then cdrom, then nic, then others) in case no
bootindex is specified.  So you can try bootindex=200, that should get
ahci to the bottom of the boot menu, maybe that is good enougth.
