eu-elflint does not seem to think that the binary is valid.

Erm, try this eu-elflint dump.
Comment 3 Bill Nottingham 2004-02-24 22:26:22 UTC 
Works with Arjan's .204 kernel.
Comment 4 Dave Jones 2004-02-25 14:54:21 UTC 
todays rawhide should also work now ?
Comment 5 Bill Nottingham 2004-02-25 16:17:01 UTC 
Yup, 1.108 is fine.
