Are there any hidden obstacles that prevent xl(4) to be extended with polling support? Otherwise, if it's rather straightforward to do (taking a driver already supporting polling(4)), I could try it starting from the end of February. But, I guess if it were so easy, somebody else would have already done it... Simon
