Interestingly, the fix from that bug report _was_ merged as commit
063a2da8f01806906f7d7b1a1424b9afddebc443 (written by me).  But then it
was removed later on(!) in commits
07c3b1a1001614442c665570942a3107a722c314 and
9aebfd6bda789891e6d296bb49b5fb32d1057f18 (written by Greg).

Apparently the check should have been moved from the core into the 
lower-level driver (i.e., ipaq.c) but it wasn't.  I don't know why; 
maybe Greg does.
