If you have enough space on /boot to add your "run-kernel" to the mix
then you do not have to reformat that partition and then you can try
multiple times if some extra kernel options turn out to be handy.
I would refrain from converting that partition to ext3 in any case.
What you will reformat during an installation is indeed "one-way".

If you do not have a suitable small partition to mount on /boot you
should be able to carve one using resize2fs.  I do not know if it is
available in an installation image but once you booted into a "rescue"
mode you can bring a network up and pull in various extra tools
(assuming, of course, that you have a network and something to put there
as a server - at least some of ftp, http, ssh, rsync will be available).

A network install should be actually faster than swapping CDs in
a slow drive, even if one available.  You need a disk space, even
if only for a time beeing, for a content of installation CDs.
In a pinch you should be able to install from a partition of your
own drive.  Whatever will later become /home likely should be big
enough.  You can always reformat that one later.  I did not ever
try something of that sort to that extent but it should work.

If you can attach that disk to some other Linux machine then
a "screwdriver solution" for preparing an initial disk layout is
also possible; aboot surely fits on a floppy.  Check first that
you indeed can boot using installation images.
