Just for testing purposes, you could try hostfs and then loopback mount your 
block device.

I boot UML like this all the time, to borrow the parent's filesystem.  (It has 
a lot of downsides, and is slower than ubd, but it requires absolutely no 
setup):

./linux rootfstype=hostfs rootflags=/ rw init=/bin/sh mem=64M

Note that this works under an Xterm because you own /dev/console, but if 
you're running it from the console you either need to 
chown/chmod /dev/console or you need to be root.  I have a script that gets 
around that, lemme dig it up...  Attached.  You don't need anything _nearly_ 
that complicated, but I just thought I'd let you know what kind of abuse you 
can do with hostfs... :)
