Those drivers would still need extracting from that 2.6.32 tree and made
to work as an out of tree driver, either as a standalone driver pack or
by updating the unmodified_drivers tree in xen-unstable.hg.

Perhaps they could be ported across and incorporated into the Squeeze
kernel directly. This would be at the discretion of the debian-kernel
maintainers and the general rule is that the driver must be already
accepted upstream which these drivers are not.

In any case I think my point, that someone needs to make this thing work
at all before worrying about how to package it, still stands.

Ian.
