SubjectRe: Dell Studio 1555 eject key does not work ( small patch to fix included )
Hello,

I suspected the same about dell_new_hk_type, but I am confused that
the rest of the fn keys work just fine out of the box. The only button
that didn't work was the eject key.

Attached is the dmidecode output.

Thanks
