I don't think sysinstall will do what you want.
However, what is your ultimate goal? To install a system with a gmirror
root drive? You can do that by installing direct to one of your drives
(ie ad0s1* or da0s1*) in the usual way and then converting the system
into a gmirror. The Onlamp article by Dru Lavigne is the best
referrence here:
http://onlamp.com/pub/a/bsd/2005/11/10/FreeBSD_Basics.html
Or else you can boot into the Fixit system, set up mirroring etc. and
then work through the rest of the installation process by hand. The
install sets are just split up tarballs and it's pretty easy to extract
a copy of a system from them.
Cheers,
Matthew
