Are you sure you need one? Are you doing a -stable release of the driver?
or just a -current? You only need a major number if you are doing a
-stable release, otherwise in -current you just don't specify the major
number in your cdevsw, and devfs will now automaticly assign you one
when you create your device node...
There are still major numbers for a few devices that may are standard
(such as zero/null), but not common...

so, you are planning do do 4.x and earlier releases of your driver?
