Do you really want to have SAF-TE polling in the kernel?
This can easily be accomplished in userspace using sg.
safte-monitor <http://gort.metaparadigm.com/safte-monitor/> can already
provde disk insertion, removal notifications in userspace and already
supports calling out to a script with the physical slot location information
(and with tweaks to the code, scsi device of the disk inserted)
There is even code in safte-monitor to identify the wwn of the devices
in each slot, although it needs updating to the latest qlogic ioctl
interface (or hbaapi).
