My fault, sorry. However Anton's device has product ID of 90x30B which
is Geyser 1 as far as I understand... But yes, we should not expect
other geysers respond to Geyser 3-specific commands.

 and I'm a very annoyed that it was
applied. It causes appletouch to continuously printk:

drivers/input/mouse/appletouch.c: Could not do mode read request from device (Geyser 3 mode)

because the Geyser 1 doesn't respond to that. The patch description also
states:

quoted

if we see 10 empty packets the touchpad needs to be reset; good
touchpads should not send empty packets anyway.

which is *TOTALLY* bogus since Geyser 1 touchpads have no notion of
empty packets, the simply continuously send measurements. One look at
the specification would have confirmed that.

Is there a way to "plug" these Geysers? Waking up the kernel
continuously is not nice.
