[linux-dvb] SAA7146 driver init.../dev/dvb not created by udev

I am running FC3 (2.6.9) with the dvb drivers that
came with the installation. Not sure why the dvb
directories are not created under /dev at startup by
udev. Everything seems to load fine for the dvb driver
and I do have the udev rules for dvb after upgrading
to the recent udev version. Any feedback on this
matter would be appreciated.
