You're right. The Port adress is hard coded in the BIOS. (RTFM ;-)

Unix has it's own drivers. So you 'only' need the BIOS to boot. No Problem
if you have a 2nd AHA1542 at 330 or a normal ST506 Controller to boot
from..

But there's another solution: You can get another BIOS for your 
desired Adress from Adaptec.

Binary Patching of the EPROM is not so simple, the adress is spread
all over the program.

You can also get the ASPI-MS-DOS Driver from Adaptec for your DOS purposes. 
You can specify the port adress in your config.sys file with this driver.
