I've heard of issues that scrollwheel emu with the trackpointer
doesn't work anymore (keeping a button pressed then use the
trackpointer to scroll) when using separated devices for pad
and pointer.

Maybe this could work when the trackpointer (including it's
3 buttons) would be driven by the real trackpointer driver and
not by the plain pass-through emu thing.

With different config i just mean sensitivity options and pad
size stuff otherwise using the pad moves the mouse too slow or
too fast.
