Maybe.  And in fact it already is!
As I delved further in to this issue, I find that not only is there a
patch in tslib to use EVIOCGRAB, but there is also a patch in the
kernel to exclude the "ABS_X + ABS_Y + BTN_TOUCH" case from mousedev,
making the EVIOCGRAB patch pointless.
And there might even be another patch in the kdrive Xserver to use
EVIOCGRAB in a different context (which might not actually be being
used, I'm not sure).  A twisted maze of little passages, all
twisted. :-)

But I am firmly against carrying patches like this which cannot go
upstream.  They can lead to subtle incompatibilities and can be hard
to get rid of.  I much prefer a solution that can work for everyone,
and I currently think the BTN_TOUCH -> BTN_STYLUS change is that
solution.  It remains to be seen which I can push into the openmoko
source tree :-)

Thanks,
NeilBrown
