You can pretty quickly determine if it is a kernel problem or a udev 
problem by adding a
'ls -l /dev/urandom' to /etc/init.d/urandom:

start() {
[...]
        ls -l /dev/urandom  # debug strangeness
        ebegin "Initializing random number generator"
        umask 077
        dd if=/dev/urandom of=/var/run/random-seed count=1 &> /dev/null

Also, only the display options for devfs were removed from 2.6.12, the 
code and config option in .config are still there.  Can you double check 
your kernel config, and make sure that "# CONFIG_DEVFS_FS is not set".  
I think if you copied an old kernel config, you could have devfs support 
still in your kernel, which might cause some strange behavior.  I'm not 
sure.
