Comment(by dsd):

 I confirm Andres's findings on XO-1.75 and XO-1.5. After enabling the
 kernel-side support for synaptics protocol, the cursor in userspace goes
 super-sensitive.

 However, the above test was done without the xorg-x11-drv-synaptics
 userspace driver available, and I suspect the same was true in dilinger's
 test. installing xorg-x11-drv-synaptics (i.e. pairing the kernel and
 userspace drivers) avoids the cursor crazyness, confirmed on XO-1.5 and
 XO-1.75, and also shown by Jon N in #11198.

 This suggests that the userspace driver is doing something to put the pad
 into "sane mode" (or just doing a huge amount of packet
 filtering+dropping). This should be investigated - maybe theres something
 simple the kernel could be doing so that things work OK with synaptics
 kernel driver and standard userspace mouse drivers.

 Also, on XO-1.5, I do (very clearly) see another problem described already
 on the XO-1.5, regardless of userspace driver in use, which is that the
 keyboard is inoperable when the mouse is being used, and for a few seconds
 afterwards (#8901).

 Andres, perhaps you could retest your XO-1.5 sensitivity problem against
 xorg-x11-drv-synaptics in userspace?
