The problem actually is that X can't process keycodes above 255. It's
a long-standing and hard-to-solve bug [1].

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.
