The bamboo exports two kernel devices that also appear as two different
devices to the driver, with two different wcmCommon devices. Only the
Bamboos should be affected by this, no other tablets.

I thought this should be fixed with Ping's "Centralize pen and touch
arbitration" patch, but it may not be. Long story short, we should just
share the common struct between the two devices.
