The ISDV4 status would be good to know (although doesn't affect patch since I deleted its reference). For Bamboo's, I've got two answer for you from personal experience. First up, the old-new Bamboo's (the 0xD0 to -0xD3 that we added support for over a year ago) support pressure readings just fine; at least as good as you'd expect for such low resolution as touching allows. With this patch set, I'm able to use MyPaint and Gimp and do some drawings with pressure support. As a side note, Henrik's patch to linut-input for initial Bamboo support kept the pressure support in and I suspect he found it working fine as well or wouldn't have included that. But next, we have the new-new Bamboo's. From my remote monitoring of packets, it looks like pressure support was removed from that firmware. So at some point, we will need to update kernel drivers and remove ABS_PRESSURE from those specific devices. And probably, we should update xf86-input-wacom to detect devices that do not advertise ABS_PRESSURE and then not create the pressure axis.
