urgh, must I?  That trashes Neil's
kmod-add-init-function-to-usermodehelper.patch and
kmod-replace-call_usermodehelper_pipe-with-use-of-umh-init-function-and-resolve-limit.patch
and probably requires repairing other stuff and sets the testing status
back to "square one".

If you have patches queued, please make the time to support them!
