AFAIK: LILO options only get passed to drivers which are compiled into
the kernel. Module parameters come from user-space tools (modprobe,
etc)

If you could boot off the floppy before, there's no reason you won't
be able to boot off of it after messing around with conf.modules. (My
reasoning being that your boot floppy must be loading it's own copy of
the driver).

If you've been using the 'rescue' floppy made by the install routine,
I don't think it uses anything on your hard-drive to boot with (until
it calls init). It has a kernel and a compressed ramdisk on the
floppy that holds kernel modules for all your block devices and their
configurations. If all your drives are connected to the aha1542, the
kernel on the floppy needs to have a working driver before it can
mount any drives.
The more I think about this, the more I'm convinced that the driver
doesn't need any arguments.

Ditto. That would be too easy :^)
It might be useful (reassuring) to have such a kernel on a boot floppy
though.
Sorry if I'm incoherent, I haven't finished my first cup of coffee
yet.
