The driver must implement two callbacks, one for suspend that backups
the card config, and one for resume, that resets the card, and restores
the previous configuration. The cisco mpi350 doesn't implement them. 
I added these callbacks in the latest version of the airo_mpi driver.  

But, you also can safely remove the cisco mpi350 driver before suspend, 
using the apm scripts. Don't forget that the interface must be down 
(ifconfig eth1 down), before removing the module, else this operation will
return a busy error. The module must be removed before going into suspend 
mode, and reloaded when waking up.

Best wishes,
