You actually lose the tap/tap-tap click and doubleclick button emulation with the new driver, and, as you note, the pressure sensitivity. Both of these issues were noted when the driver was posted for review. It semed the consensus at the time that until at least the tap/tap-tap was brought back (via software emulation), the driver would not be replaced, only optioned. You can check the list archives for details, I think. The "pressure sensitivity is, I think, really an area sensitivity and not a real pressure sensitivity (I can't imagine actually losing an axis of data!). That would mean, like the tap/tap-tap, it could be emulated in software. Probably the best thing to do would be to disassemble the BIOS on your box, knowing the difference between the older driver's interface, and use the same techniques that were hidden from the older driver (and "just built in" instead). -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
