If you check the archive's I've had a similar problem.

Possible answers:

Compile the to-be-loaded-2nd driver as a module and keep the first builtin
Use devfs (it lets you pass a 'scsi=driver1:driver2:...' to the kernel,
controlling load order)

There are devfs 2.2 patches and 2.4.1 includes devfs natively; I chose
2.4.1 and it worked.
