These changes provide better support for early-2011 Apple Macbook Pro
laptops: native resolution by specifying the vid & did in /lib/vgadb,
as well as providing an 'appletouch' mouse option, which stops i8042
calls for the internal trackpad.  See
https://blog.fallglow.com/misc/mbpro/cs8390.kmesg for an example of
what is generated when the vgadb entry is lacking and the i8042 calls
occur.

I hope to implement rudimentary multi-touch for the internal trackpad
so that an external 3-button mouse is not required.

There is still an error thrown when initializing the keyboard early on
('i8042: kbd init failed'), but I haven't tracked down what is calling
the i8042 reset whence the error message is generated.  Additionally,,
there is an issue with amlmapio.
