Got some good hints from Nate @ Red Hat as well. One solution is to
detach the external disks and add the following line to modules.conf:

options aic7xxx aic7xxx=reverse_scan

Then rerun mkinitrd and attach the external disks again.

Another solution that seems to work is to disable the bios completely
on the external Adaptecs, but I think I would prefer to not do that,
as I won't see potential disk problems as soon, at boot up.

Other then that there doesn't seem to be any way around having to
update the raidtab file if you insert a new disk in the middle of the
scsi-chain (to keep the device names consistent with the contents of
the superblocks), as all the disks after the inserted disk will change
their device name.
