OK. I have numbers for Kubuntu, Ubuntu is in the works :)
Total memory: 239 (really 239480 as reported by free/top, I will round it).
Right after booting live CD: used=235 free=4 shared=0 buffers=0
cached=80 swap used=20
After "swapoff -a": used=235 free=4 shared=0 buffers=10 cached=90
I will omit used, buffers, free and shared from now on, as they do not
change significantly.
After starting Ubiquity: cached=81
Ubiquity step "locale"->"timezone" (Polish locale): cached minimum=68
Ubiquity step "choosing partitioning type": cached=61
Here I accidentally restarted Xserver by pressing Ctrl-Alt-Backspace :/
On the second run when I got to "custom partitioning" step (Qtparted),
the numbers were: used=225 free=14 cached=62.
Going to "Ready to install step": used=236 free=4 cached=52.

And that's all, since then swap was set up.
I guess I will have to write a script to gather exact numbers as I might
have missed some minimum during creating filesystems.

All memory numbers gathered from tty console (not using Konsole) using
top/free.
