Installing multiple operating systems on a single Virtual Machine with VMware Server

I'm currently running 3 operating systems on a single virtual machine, using VMware's new Server product. I've currently got FreeBSD (from the FreeSBIE live CD), Minix 3 and Ubuntu installed and running without any problems (apart from a deluge along the way). Providing a gateway to them all is the free XOSL 1.1.5 bootloader (official site currently offline).
4 virtual disk images are behind this configuration (1 IDE, and 2 SCSI).
