debug=2 didn't work.  dmesg said:

  hid: `2' invalid for parameter debug.

With debug=1, I get the following output.

But first, info:

kernel 2.6.25.6 - no extra patches

There are 6 six keys which do not work at all:

Also, the "Power" button keeps repeating once pressed:

There you are.
Let me know if there is anything else I can do.
