Yes, that's possible, even with the X server itself (see
http://os.inf.tu-dresden.de/L4/LinuxOnL4/inaction.shtml).

Wow, that's adventurous. ;)

This is not going to work for various reasons, first that L4Linux cannot
be loaded directly but needs to be started by the loader. Others are,
that there are quite a few modules missing.

You cannot run L4Linux under Fiasco-UX from /dev/hda as your Linux host
has already taken possession of this device. You would probably have to
hack the host kernel...  But for L4Linux on Fiasco-UX one can have a
disk image file.

I suggest that you look into l4/tool/runux. Copy config.template to
config.local and edit it appriately. Then there's a 'lx' script with
which you can start L4Linux in various configuration (with con, dope or
no output, with net or without, with blockdevice or without, etc.). When
building L4Linux make sure that you do not include any drivers,
disabling PCI should be a good start.
