FreeBSD 2.2.9-RELEASE:
4MB: Boots / Sysinstall dies while probing devices.
8MB: Boots / Successfully installed the default minimal distribution set.
Mem: 3764K Active, 432K Iact, 1472K Wired, 244K Cache, 420K Buf, 184K Free

I also did a minimum disk space study using FreeBSD 6.0-RELEASE back in January:
* 1st column of numbers are from the VM disk image file, outside
FreeBSD. This is significant because it records the total disk space
FreeBSD needed *during* install.
* 2nd column is from inside FreeBSD with "du -m" after install.
* All numbers reported in megabytes.
