Not creating /dev entries at boot

[David D. Hagood]

I'm having a weird problem with rawhide that started a couple of days 
ago - none of the directories managed by udev are being created at boot. 
No /dev/tty*, no /dev/pty*, no /dev/mem, no /dev/random, no 
/dev/ttyUSB*. As you can imagine, the system is not very happy.

udev on start is saying "kernel too old for this version", which seems 
strange as I am running 2.6.14.2 - if that is "too old" then something 
is seriously wrong with the udev folks idea of "old".

Has anybody else seen this, and does anybody have any suggestions?
