Personally, I'm happy to relicense our 'unprivileged guest' drivers
under a BSD-style license. This would include at least the following
files that contain no Linux code:

linux-2.6.8.1-xen-sparse:
 drivers/xen/netfront/*
 drivers/xen/blkfront/*
 drivers/xen/evtchn/*
 drivers/console/*
 arch/xen/i386/mm/hypervisor.c
 arch/xen/kernel/ctrl_if.c
 arch/xen/kernel/evtchn.c
 include/asm-xen/ctrl_if.h
 include/asm-xen/evtchn.h
 include/asm-xen/hypervisor.h
 include/asm-xen/multicall.h
 include/asm-xen/suspend.h

I consider this the least we can do given the lack of documentation
that would allow OS porters to roll their own. :-)

There is the issue that there are bits and pieces of other people's
code in there as well --- e.g., Christian Limpach, Mike Wray, Mark
Williamson. But I don't foresee any problems.
