Excellent! I'll close my older version of the same thing.

If someone is feeling eager, many callers could change to
try_then_request_module(), eg:

diff -urpN --exclude TAGS -X /home/rusty/devel/kernel/kernel-patches/current-dontdiff --minimal linux-2.5.69-bk13/drivers/net/ppp_generic.c working-2.5.69-bk13-try/drivers/net/ppp_generic.c

Thanks!
