I've never had a problem with it. It can hang on unbind if the device in
question is in use but as soon as you free up the device (i.e. close the
application which accesses it) the script will continue.

The -xen0 is intended to be a mostly statically compiled kernel with
drivers for the most common hardware. If you want a modular kernel you
should be using the -xen kernel.

The xen-unstable build system will do the download phase for you. You
can also use the "make CONFIGMODE=menuconfig linux-2.6-xen0-config"
style targets.
