RE: [Xen-devel] [PATCH 1/3] Add Summagraphics Tablet emulation

Keir-

Yes, the 3 patches are independent so you can apply them as you wish.

I'm not sure what your concern is about the touchpad patch.  There was
code to emulate a touchpad in the code but it was all wrong and didn't
work, I basically had to re-do all of the touchpad code to get this to
work.

I'm talking to Johannes Schindelin about getting touchpad emulation put
into straight `qemu' so, eventually, we won't need any special code in
the Xen version but that won't happen for a while and this patch gets us
working until then.
