"ThinkPad Extra Buttons" device not detected on ThinkPad X61

[Ben Liblit]

My ThinkPad X61 has the "thinkpad_acpi" kernel module loaded, which 
correctly detects a "ThinkPad Extra Buttons" input device and creates 
the expected structures under /sys/class/input/input<n> for some <n>. 
However, hald does not include this input device in its list due to its 
failure to understand the SW_RADIO input type flag.

Bug report <https://bugs.freedesktop.org/show_bug.cgi?id=13803> has a 
patch ready and waiting to be applied.  It's been sitting for over a 
month now.  Can't someone please apply this to the main tree?
