You could try to mount a 6.2 iso-file and use the sysinstall from there,
if that does not work due to library dependencies you could partition
the disk by hand using fdisk and disklabel (or do that with the 4.8
sysinstall). After mounting the new disk to /mnt etc. you can extract
the kernel and userland using the script you will find at the
set directories in I think
you only need base and a kernel.

Only drawback is you will not be able to use UFS2 I guess, because the
4.8 newfs doesn't know about that. But maybe someone has a solution to that.

You could also use qemu to prepare a freebsd6 system and use dd to write
it onto the second disk.
