With the default configuration yes.

I recently tried to install FreeBSD 6.1-PRERELEASE on a
Pentium 90 with 16 MB RAM, and hit the rebooting problem as well.

I moved the harddisk into a more powerful machine,
installed FreeBSD there, build a lighter kernel and
put the disk back.

NFS mounting needed a work around:

but the rest worked out of the box.

In your case it's probably easier to create a disk image
in Qemu, copy it to a CD and then use something that
boots from a floppy, supports the CD-Rom drive and brings
dd with it, to "install" the image. 

Depending on your partition layout you may even
be able to use your old FreeBSD installation to do that.
(I'm not sure if it's possible to use FreeBSD to overwrite
the partition it's running from).
