I've had the same problem to re-appear like a week ago. Since then I
have been investigating this issue further and am attaching a new patch
which survived for the last 5 days.

First of all the left mouse button is just bit one in the status byte
(the last byte in the package) as was discovered by sven anders.

Second, when appletouch after 10 idle packages does a mode reset, the
data should marked invalid (then on the next touch the driver re-gets
data once without moving mouse etc). This is important if the touchpad
conditions change (e.g. long time no touch + bigger temperature change).

However sven figured out that bit 3 of the status bit should actually be
used to re-get touchpad data.

So if you want a working minimally intrusive patch use this one.

I will in future only contribute to svens much more mature work.
