Not currently.
On x86 absolute mode is set on psmouse-base module initialization.
There's no config option here, if you build the kernel with psmouse and
you have a synaptics touchpad you can use it only in absolute mode
(mousedev takes care of a proper absolute to relative conversion).
X driver opens event interface and check for ABS_X, ABS_Y, ABS_PRESSURE
and BTN_TOOL_FINGER bits with an ioctl. If success it hooks the device
with another ioctl to evdev.
