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

[Rezwanul_Kabir]

Hi Matthew/Islam

   I don't know how Ubuntu 10.04 fixed the issue, but from my communications with the BIOS team, I think 
 Islam's patch would be acceptable. "buffer_entry[1] == 0x0" would indicate HotKey events on these platforms.

Thanks..
