Assuming no one's replied to this yet (I'm still catching up on my mail):

1) I thought that GENERIC kernels had been modified to accept swap on 
differing drives from whatever one your root partition is on, but you 
might need the proper line in /etc/fstab

2) You can hard code in your disk configuration with a line like:

options	config	root on /dev/sd1a swap on /dev/sd2b dumps on /dev/sd2b

or something a little similar to that.  There should be examples in some 
of the config files in the mac68k source distribution.

Later.
