All that I know you can't make them coexist. They use the same
hardcoded block numbers for there partition tables just like anybody
else. You can't have two block 0's.

Try exchanging the ramdisk used by redhat with the root.bin file used
by debian. After that you should have a debian install disk. I hope
the installation copes with BSD partitions, but if not, its a bug.

/usr/src/linux/... is a great source of information. But forget about
getting both partitioning schemes work together, it most like wont be
possible anyway.

For Linux you don't need PC style partitions, BSD partitions are just
fine. The Debian installdisks should recognise the BSD partitions, but 
might not, which would be a bug. Creating BSD partitions directly is
not possible with the current install disks, but maybe you can work on 
that. :)

May the Source be with you.
