At least for Bamboo's with product ID between 0xd0 and 0xd4. In my testing of an 0xd1 device, pressure works fine (low pressure and high pressure work great. Not much middle pressure sensitivity. Multi-touch will increase pressure reading. All pretty common behaviour). I don't use the pressure in day-to-day usage but do use it to drive testing of pressure features of some apps/drivers and so don't want to lose it. >From looking at the touch data on Bamboo's > 0xd4 that people have emailed me, it looks like pressure data was removed from firmware so a version of this patch will be useful for those. But that patch needs to also change the way it parses the touch data to reduce from 8-bits to 1-bit.
