Some Wistron based laptops need us to explicitly enable the 'Dritek
keyboard extension' to make their extra keys start generating scancodes.
Originally, this was just confined to older laptops, but a few Acer
laptops have turned up in 2007 that also need this again.

Dmitry,
Can you please check the i8042_command() call is correct, I'm having
trouble getting my head around the call semantics. What I'm trying to do
is send the command 0x59 with one argument, 0x90.
