I've solved the above problem in the latest patch 
(file2alias_hex_or_bcd.patch) which automatically detects if a driver 
entry is supporting a hex bcdDevice rather than a bcd one and adjusts 
accordingly.  Thus, for all normal devices, there is now no change at all.

In the process I discovered another bug.  'devlo++' and 'devhi--' are 
used.  However this number is most often in BCD format, so ++/-- won't 
work.  A second patch (file2alias_bcd_increment.patch) resolves this issue.

Again, questions/comments welcome.
