Only LX and SX (of all the boxes with CPU older than EV6) had the
Adaptec driver added to their SRM console.

I agree.

The suggestion was also made to use modules; that way, you load the
SYM53C8XX driver *before* the Adaptec, and you get what you want.

If you always intend the Symbios to be scsi0, then you could get away
with the following, and not have to muck about with an initrd:

1. build a kernel that has Symbios driver built in, and Adaptec driver
   as a module.

2. because it's the ONLY SCSI in the kernel, SYM53C8XX becomes scsi0

3. after boot, load up the Adaptec driver module, and get scsi1.

As I said, its dependent on the order in which the SCSI drivers are
asked to probe, and that order is defined in the SCSI code.

Try the method suggested above (SYM53C8XX builtin, AIC7XXX module),
and I think you should be OK.
