Nope, it's Fedora 15 without all the Ubuntu fakekey stuff. The event
is coming from a thinkpad_acpi-generated input device for sure.

I'm on 1.41, and the latest is 1.44 (I'm at a conference now, and
can't update the BIOS right now). I can update this when I get home if
you like in one weeks time. I'm also pretty sure most non-geeky people
don't ever update the BIOS, and it should probably work without a BIOS
update too.

I've attached my dmidecode. Thanks for any help,

Richard.
