Thanks Giuliano and Takashi for the replies.

The reason for my quietness is I decided loading/unloading the module was 
a hack so I followed Takashi's documentation, aiming to implement some 
kind of suspend/resume.

However didn't have a great deal of luck; it's made especially hard with 
not having a separate serial console or way of viewing debug messages when 
the machine locks. It seemed that the amount of de-initialisation affects 
the ability to reinitialise the Layla 3G card from scratch. Then I ran out 
of time.

It would be great to see the patch, I'd be very happy to help with 
testing. Thanks for your work on this.
