Actually Alexey has another patch in bugzilla (#10919) which resolves
this issue in a better way.  It avoids polling altogether, which is good
because it means you get events immediately.  My laptop has backlight
adjustment hotkeys with hardware autorepeat, so it looks really jerky
with polling.

So I think I should withdraw my patch and leave this to Alexey.  I've
tested his fix on my laptop and it works fine.  It needs some more work
though - e.g. at the moment it spams the kernel log.

Thanks,
Alan
