[1.] One line summary of the problem:    

No keyboard control on the console or in X

[2.] Full description of the problem/report:

No keyboard control with devfs enabled on boot up.
Is it time to give up on devfs? (This is not flamebait.)

[3.] Keywords (i.e., modules, networking, kernel):
Keyboard console

[4.] Kernel version (from /proc/version):

Linux version 2.5.36 (root@the-penguin) (gcc version 2.95.4 20011002 (Debian prerelease)) #0 Wed Sep 18 15:46:06 PDT 2002

[5.] Output of Oops.. message (if applicable) with symbolic information 
     resolved (see Documentation/oops-tracing.txt)
No messages or oops.

[6.] A small shell script or example program which triggers the
     problem (if possible)
N/A
[7.] Environment
Debian unstable devfs enabled on bootup.

[7.1.] Software (add the output of the ver_linux script here)

If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.
