=46or Nokia N900 (and Maemo system) we are using older udev version=20
(0.125), so here should be support for firmware helper.

And if some new udev version will not work, we can just revert=20
back to older working... No need to use super-uber-fantastic=20
systemd-udevd software which removing old useful code.

So looks like adding new rule file to udev for handling firmware=20
requests from kernel could work...
