My first kernel patch

OK, so it's not really anything big. In fact, it's really just a copy and paste (almost).

So, way back when acerhk actually compiled, I was able to use the extra keys on the laptop. These were the volume, media, mail, etc. keys. Now with Fedora and a much newer kernel, it no longer compiles.

Every once in a while, I tried to see if I could fix the compile, but never really got anywhere. But then I found something interesting in the kernel sources. In drivers/input/serio/i8042-x86ia64io.h there was something about a Dritek quirk. I recognized the name as something the acerhk driver also supplied. So, I rebooted and tried that out using i8042.dritek=1 and voilà, the extra keys worked. And a quick copy and paste later and I had me a patch. Just like that:
