It's easy to boot more os'ses from one disk.
Netbsd got a nice tool for this.
Of course, first divide the disk into several slices and install the os'ses you like. Next you can install the netbsd bootmanager, works great, can boot nearly all i believe. Do it like this:

Imagine you got an ide disk as first disk.
fdisk -i -c /usr/mdec/mbr_bootsel wd0
disk -B wd0

Answer the questions needed and there ya go.
Btw, i must say this is an rtfm matter, on the netbsd pages it is nicely described. Hope it helps.
Bye,

Mipam.
