I have both RH 9 kernel 2.40.8 and 2.40-13.9 (the latter does not accept
my nVidia driver, so I don't use it. I'd better get rid of it.)

I suppose kernels (have to) reside in distinct partitions?

Aha! So that will be the 'come-back' of Mandrake 9.0. 
(I thought about replacing that by Mandrake 9.1.one of these days)

"Then I have Mandrake 9 sitting somewhere, I guess that's hda6?
Right! I admit I had a paranoid feeling about those two "swappers". 
Mandrake's SWAP was installed first. RedHat's installer didn't notice it
and joined it's own SWAP, whithout asking any questions.

My guess was this happened because Mandrake's EXT 2 would not be
compatible with RED HAT's EXT 3. That's why I did not dare to remove
one.  Suppose I did remove one, I then have to point either distro to
the reamining SWAP to be used, right?  I hate to think about the
consequences if it would not find the SWAP.
