On my A20p, the following works: boot with dvd drive; suspend; insert
extra battery instead of drive; resume; work (just don't do anything
that would access the drive); suspend; insert dvd drive again; resume;
access drive

This is on 2.4.18 and I can't remember having done anything special to
enable it. Below an excerpt from the kernel config that might be
relevant.

good luck, til
