I have 486 boxen running both 2.2 and 2.4 kernels, which seem to work much
more efficiently than the ancient 2.0 kernels. As far as distributions go,
Debian seems to be better suited for installs on small hard drives, but I
managed an install of RedHat on a 120MB drive once (and I swore I'd never
do it again).

The 2.2 and 2.4 Linux kernels support IRQ sharing, so it should work "OK"
so long as you don't attempt to run the shared ports at very high baud
rates.

I have to agree, intelligent serial cards really help. I use a Digi in one
of my systems.
