tags 637978 + patch
thanks

So, after some more work and thoughts, here is a new patch proposal 
(attached).

Discarded, for performance reasons: keeping the code self-contained in the 
postinst allows me to save the `lpinfo -m` once for all updates.

Done and tested locally with one driver.

"To be done", of course.

Please comment on the attached patch; 

cheers,
