Microsoft Sidewinder X4 and X6 gaming keyboards offer special keys,
which now can be read via sysfs, so they can be handled by user-space
tools. Profile switching support, LED support and macro pad
support (X6 only) are implemented aswell.
Both keyboards have been tested and run perfectly well.

+Description: This file is read-only and outputs an unsigned long integer.
+ Every bit individually represents one of the S1 - S6 extra keys on
+ the Sidewinder X4 and S1 - S30 on the Sidewinder X6. The least
+ significant bit represents S1 on both gaming keyboards, the most
+ significant bit represents S6 on the Sidewinder X4 and S30 on the
+ Sidewinder X6 keyboard. Multiple special keys can be pressed at the
