SubjectRe: [PATCH 08 of 12] xen-console: add save/restore

-tip testing found the following xen-console symbols trouble:

ERROR: "console_drivers" [drivers/video/xen-fbfront.ko] undefined!
ERROR: "get_phys_to_machine" [drivers/video/xen-fbfront.ko] undefined!
ERROR: "get_phys_to_machine" [drivers/net/xen-netfront.ko] undefined!
ERROR: "get_phys_to_machine" [drivers/input/xen-kbdfront.ko] undefined!

with:

http://redhat.com/~mingo/misc/config-Mon_Jun__2_12_26_38_CEST_2008.bad

get_phys_to_machine can indeed be exported but i'm less sure about the
console_drivers export ... The temporary fix below resolves it for now.
