No need, the problem resolved itself by de- and reactivating USB in
VBox (thanks HPS). This is definitely not a FreeBSD-related problem, I
have been having problems accessing a specific USB drive from within
VMs, both FreeBSD and OpenSolaris, and that one appears to have been
the problem here as well.

So, the current status is: The cleanly installed 8.0-RC2 works, the
updated one not. So this is either my bad or the freebsd-update did
something wrong. I'll try to find out what and keep you posted.

thx for all the suggestions, M.
