Hmm.  I just excuted the above commands on 1.930 (on a 2.6.1 kernel) and
it works fine.  Obviously something must have changed since 1.172 and 1.930.
I do not have a 2.4 kernel to test on.  I will try and build a 2.4 environment
to test and debug on.

My gut response is to tell you to upgrade to 1.930 (which is based on a
2.6 kernel).
