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