sorry but it failed with the following:
Hmm... Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|--- identcpu.c Fri Mar 5 03:28:32 2004
|+++ identcpu.c.new Tue Mar 9 23:11:53 2004
-------------------------
Patching file identcpu.c using Plan A...
Hunk #1 failed at 572.
1 out of 1 hunks failed--saving rejects to

done
i haven't looked through this identcpu.c.rej yet but
i'm attaching it to this email
