With console access that shouldn't be too hard.
My suggestion would be along the following lines:
- Make a disk image with the FreeBSD installer using my iso2diskimage
script at <http://borderworlds.dk/utils/>.
- Add an entry to your GRUB configuration that will use memdisk from
the syslinux package to load the disk image.
- Reboot and select the newly created FreeBSD installer entry in
- Install FreeBSD
The installer will run completely from RAM when booted so you can use
the entire disk for FreeBSD. However, once sysinstall starts writing
stuff to the disk you will no longer be able to boot the installer, so
make sure to do it right the first time. :)
