Mandrake's kernel is fine for Sony laptops once you turn on acpi in
/etc/lilo.conf. Only issue I have with it is swsusp.

ext3 and ext2 are backwards compatible -- you can mount an ext3
partition as ext2 and have no problems.

Given this setup, I would seriously consider starting over and
reinstalling :-( Next time try something more like this:
/ = 1G
/usr = 7G
/home = whatever's left.

You can get away with a smaller /usr if you're not messing around with
lots of different software, but it sounds like you're looking to play
with stuff :-)

Another option, if your windows partition is fat32 instead of ntfs you
can always use it for space. Just edit /etc/fstab and change the mount
point to something like /home/dan/windows.

A lot faster to just burn a Knoppix disk :-)

Lots of cool stuff out there. You can look at premade stuff like
MondoRescue, tomsrtbt, trinity rescue kit (my favorite as it includes
Win2K SAM hacking tools), or you can roll your own. Just make a
floppy-sized bootable image and write it to the CD using El Torito, then
fill the rest of the CD with the goodies you want. The good folks at 
http://leaf.sourceforge.net are always messing with this sort of thing
and can give pointers, and I've also got some cd-creation notes on my
Vaio page at http://www.monkeynoodle.org/comp/vx88.
