Sorry, I haven't been very responsive this week.

I have been in touch with Dmitry Torokhov who maintains the Input layer
for Linux. He suggested a few changes, and I wrote a new version of the
patch based on his suggestions. It also has a variant of Dave's 'button
router'. This is now on the linux-input mailing list, and I hope for
inclusion in Linux.

Nevertheless, I'd appreciate it if you guys gave the new version a spin
and verify that all your favorite bugs are gone. Maybe someone could
compile a readymade .ko for everyone to test with the stock ubuntu
kernel?

Thank you guys for helping me on this!


A few minor details:

* The weirderbit is used as a button bit in some models.
* Waiting for a seventh byte after six have been received is not an option. The 
PS/2 driver will force desync in this case. I.e. detecting the packet lengh 
will need a redesign at a deeper layer. Nevertheless, if you don't press all 
three buttons, the driver should work :-)
* Dave says that the seventh byte is not even necessarily helpful.
