"You need: Linux kernel 2.6.30; a computer with a
Broadcom 5974, Stantum, NTrig or DiamondTouch surface (the HP
TouchSmart tx2 has a Ntrig surface, but you need to get the
appropriate firmware from the NTrig site); our NTrig, Stantum, or
DiamondTouch driver, or the Broadcom 5974 driver from Henryk
Rydberg; our demo code."
