  I'm afraid that mdev and udev no longer work with old kernels that 
don't support the DEVTMPFS option...

  mdev and udev don't create device nodes; they only do something 
configurable when a hotplug event happens.

  That said, you can create custom mdev/udev rules to create device 
nodes. But it's all manual - and much simpler to just create the device 
nodes manually.
