Works out of the box with the ite-cir driver in 2.6.39, but stops working after a suspend/resume cycle. Its fixed by simply reinitializing registers after resume, similar to what's done in the nuvoton-cir driver. I've not tested with any other ITE variant, but code inspection suggests this should be safe on all variants.
