 on three or four mechanical keyboard 1.75 models i've tried:  the cursor
 begins to "wander" on its own as soon as its put into ebook configuration.
 this can be observed both in OFW with "test /mouse" or under X.  the
 kernel identifies these touchpads as "ImExPS/2 Generic Explorer Mouse" --
 they may be AVC touchpads, since our kernels don't include the Sentelic
 driver that would be specific to the AVC touchpads.

 i've found one AVC laptop in the cambridge office, and it too exhibits the
 ebook wandering behavior, though it feels like it's to a lesser extent
 than on the 1.75 models.

 the two membrane keyboard 1.75 models i've tried do _not_ exhibit this
 behavior.  those laptops both have Synaptics touchpads.
