I agree that virtualising FreeBSD is useful but I suspect your chances
of getting guest patches for FreeBSD 4.x are very low. FreeBSD 4.x is
no longer supported by the FreeBSD project and there are significant
changes in the kernel architecture between 4.x and later versions.
For new features to be added to FreeBSD, they must be first added to
the latest version and then back-ported to older versions - the
backport to 4.x would probably require significant effort.

Note that FreeBSD does not have block-mode devices.
Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
