The problem actually is that X can't process keycodes above 255. It's a long-standing and hard-to-solve bug [1]. > What was the last working kernel, and what was the first broken one? > Did you try cloning Linu's tree and doing > git log <known good>...<known bad> -- include/linux/input.h No, because I don't remember when it went wrong (I thought I'd look at that later, without pinpointing the last change; I know, that was stupid). But I just found a patch for xf86-input-evdev [2], so I'll first give that a try. Nevertheless, I'll report this to LKML anyway. Thanks.
