In my experience, the installer prompts you to proceed at each step, and
offers alternatives.  It does NOT "not go forward unless [some other
partition] is formatted".  It _does_ offer a default path forward that
formats succeeding partitions, and you may not have realized that you
did not have to follow that path.

You should be fine re-using the same swap partition from both SuSE and
Debian.

It sounds like you have Debian and SuSE configured to use that partition
for different purposes.  Check your fstab file in Debian AND in SuSE.  You
may still have to reformat it for swap when you are done.

reiserfs doesn't "like" anything about other partitions... it has no
opinion on matters outside its partition.  However, fstab may be messing
you up.
