I'm having the same problem.  I upgraded to Hardy last night and the 
mouse stuff doesn't work.  The Fn keys are doing that by design.  I 
decided to have the special macbook keys emit corresponding events 
rather than the F# event.  You can switch this by changing the TRUEs on 
lines 270-275 in multitouch.c which begin with key_down to FALSE.  This 
may be a kernel upgrade issue actually.

Another person had the 0230 hardware but they said it wasn't working.  
The bug in usbreader may be a result of the Hardy upgrade.  I have not 
run any of the tools on Hardy.

Development is going decently.  You can see the progress in svn of 
sourceforge.  Since alpha I've improved the click detection and switch 
to openusb which is threadsafe as opposed to libusb.

It'd be great to get it work in Hardy.  :-D  I think one of the next 
things that needs to be done is to hook up a configuration interface 
through touchd.py.  That would involve expanding the dbus stuff.

I have not heard of any differences between 0230 and 0231 but would love 
to hear if there are any.

I've forwarded this to the touchd-devel mailing list too.

Thanks,
