	I think we should compile polling support in unconditionally and
	allow it to be switched on/off at run-time.  One more thing where
	people do not need to recompile the kernel.

	Another thing, don't know how to go about this in code since I
	have not looked at it for a while now; would be to automatically
	fall back to polling mode if driver doesn't work in interrupt
	mode.
