Hi, I have found that one of the patches, keyboard or modem, from http://the.earth.li/pub/e3/2.6.19, break gpio interrupt handling (as Jonathan McDowell said*, he found it conflicted with the FIQ keyboard patch). Without them, both gpio-switch and gpio-keys versions of a platform device for ams-delta hook switch do work for me. I can try to provide patches against omap git tree if there is any interest.
