Yup.

I'll see if I can make a Xen domU version of the kernel next week, I 
happen to be playing with Xen for some other projects I'm working on.

Nowhere near that bad, it's just some of the packages in openssi-lenny 
(none of which are particularly user-facing) and all the packages in 
openssi-lenny-extras:

    Package: gnome-power-manager
    Package: grub
    Package: hal
    Package: libdevmapper1.02
    Package: libsane
    Package: libsane-extras
    Package: udev

That's the idea.  This is a place where we seem to have some bugs at the 
moment, some multi-threaded processes seem to be showing up as 
unmigrateable.

Not yet.

What driver does it need?  What kernel version does it come in?

Could be done.
