Don't know - my machine is still building (probably due to my utterly
slow download speed of around 25KB/s vs. your 8.5MB/s)... I'll give it a
try when it's been built.

Because no one asked for it before? [Most of the major players in Xen
development are from SuSE/Novell, RedHat and as such will not really
care what version of kernel - as long as it's not too far off their
choice - as they upgrade to whatever kernel their next release will be
and back/forward-port the necessary patches as needed].

You could try asking the question on Xen-devel mailing list before
submitting a patch. This is really a question for Xen-devel, not
xen-users.
