There are generally four possible reasons why a driver for particular 
hardware is not present:
 1) the tehnical information to write the driver is not available from the
 2) the current driver developers do not have a sample of the hardware
    to test against.
 3) the current driver developers do not have the _time_ to do the work.
    remember, this is a volunteer effort.
 4) no one with the time, and resources,  to do it is interested in doing so.

Items 1 and 2 account for a -lot- of 'missing' device drivers.

Which of the above can _you_ help with?   <grin>
