I just tried this on a freshly unpacked and configured (but not
compiled) 2.6.16-rc1, and I observe a similarly strange, though
different, behavior:

hyperion:/home/khali/src/linux-2.6.16-rc1 # ls -l /dev/null
crw-rw-rw-  1 root root 1, 3 2006-01-18 09:30 /dev/null

See the permissions change? I wonder what caused that.

The trace above is from a SuSE 10.0 on x86_64. Then I tried on my
laptop which has a Slackware 10.2 on i386, kernel had been built in the
directory, and result is the same:
