Try running "depmod" before trying to modprobe the driver.  If this
works then the problem was the driver wasn't known to the modprobe
configuration.  depmod is often run if you install a driver to extras.

Also, try using insmod using the fully qualified path to the driver. 
 If this doesn't work then your driver is not compiled correctly.
