Would you like to submit the Driver Test Cases to LTP ? Or, if you have your Driver test cases written in C, we can port to LTP and have it inside the LTP package.
You can also check out the following links for more info, and can always ping me for anything:
http://ltp.cvs.sourceforge.net/ltp/ltp/testcases/kernel/device-drivers/,
http://ltp.sourceforge.net/documentation/how-to/ltp.php?
