Bamboo's with Product ID's > 0xD4 return values unrelated to pressure
in touch 1 pressure field.  They also report touch 2's X/Y values
shifted down 1 byte (where pressure was).  This results in jumpy
1 finger touch and totally invalid 2nd finger data.

For touch detection, switch to a Touch Present single bit that
all versions of Bamboo support.

For touch 2 offset, calculate offset based on a bit that is set
different between the two packet layouts.

Since touch pressure reports were removed from driver, there was
no need to be reading pressure any more.

Applied, thanks Chris.
