I recently upgraded to FC5. I'm finding that each time I boot, my

I have entries in /etc/modprobe.conf. I thought this was how devices
are mapped to drivers.
alias char-major-81-* videodev
alias char-major-81-0 ivtv
alias char-major-81-1 bttv
alias char-major-81-2 cx8800
However, since upgrading to FC5, this doesn't appear to work anymore.
Is this a modules.conf thing or a udev thing?
How can I make my video devices order boot up the same each time?
I don't think you need to... The problem is to get udev to give the same
name to the same device every time, isn't it? I can't tell you how to do
that, but I'm sure it can be done. And someone will say "you don't know
how to do that?" and tell you ;-)
Most of the video modules that I have used have options on the
module load that you can put in modprobe.conf to specify which
/dev/video[012345] device that you want it to use.
do "modinfo modulename" and it will give you a list of options,
it may allow you to specify the video device that you want it
to assign that to. The option is usually something like
video_nr default is use next available.
I believe the alias tells modprobe to load that device if someone
uses that other name, it does not tell the module to use
any specific device.
I know I have forced one web cam to be video5 and another to be
video0 and anther to be video1 on the same machine, and they do
seem to stick, but it requires using the module specific options
for each device.
