Have to wonder if it wouldn't be worth e-mailing the VMware people about
this -- they'd probably rather know in advance if there's a potential
problem hosting future versions of FreeBSD under VMWare.  If someone has a
commercial license, it would make sense submitting this via a trouble
ticket, as well as providing the VMware support people with some brief
directions on installing 5.0.
