+The pmw33660 and pmw3389 use the same registers and timing and such.
+The only differences between the two is the firmware used, and the
+range for the DPI. So add a semi-secret hack to allow use of the
+pmw3389's firmware blob. Also, can set the max cpi range too.
+This should work for the 3390 and 3391 too, in theory.
