[okl4-developer] adding a wombat driver

[Jorge Torres]

Hi Hal, okl4.org,

Thanks, I've made the changes, and I now know that new driver is being
compiled, I've tested adding an error to driver's code and build halts
because of such error,  what I'm not so sure  of, is  if the driver is
being included  to  the  kernel,  I  have this  printk at the  init_module
function and  nothing happens  on kernel initialization  prints,  do you
know a way of testing if one's drivers have been executed?

Thank you very much,

Jorge
