The kernel did not change, odds are you userspace tools did.  What
distro are you using?  A number of them have switched away from using
the hotplug package, and use udev only instead.

While others remain compatible with the old scripts.

Either way, this isn't a kernel issue.  Try asking on your distro
specific mailing list.

Oh, and if they are using udev, a simple udev rule will work just fine
for your device to load it's firmware, if you need help with this, try
asking on the linux-hotplug-devel mailing list after reading the udev
documentation.

thanks,
