The change was made with udev-059 and continued in udev-060. Future versions 
will follow it. Read changelog and release-notes files provided inside 
udev-059 package and future udev versions (like udev-060). This change is 
permanent. However it looks distros are not ready for using new udev.

I did not tested it with other hotplug hardware - I only have my modem which 
only work with my patch.

You can read specs of my modem here: http://www.speedtouch.com/prod330.htm
The firmware " Embedded Firmware for Linux users" is on this page: 
http://www.speedtouch.com/support.htm

Uploading of such firmware is impossible without my patch. The udev-058 and 
earlier do not need patch.

Kay Sievers mentioned in changelog about new changes. But Greg KH written 
gentoo config file which 1 line I used in lunar patch. So it looks udev team 
knows about changes they introduced :-)

The patch is designed for lunar and it applies Gregs command if it is not 
available in config file. Otherwise it is not used. For people who do not use 
hotplug devices the patch is transparent == do nothing.
