I just ran into the same problem. In xorg.conf I explicitly told the synaptics 
driver to use "psm" and "/dev/psm0", but the error message would suggest that it 
uses "event".

Also, I tried to change the source code of the synaptics driver (synaptics.c) 
and hard-coded "psm" as the only driver, no matter what xorg.conf says. 
Synaptics still would not start, but this time complaining that no device was 
specified. Please note that I had "Device" in my xorg.conf, but the error 
suggests that the driver ignored it.

It almost seems that no matter what options I pass to synaptics, it does not 
receive them. Is it possible that Xorg's option retrieval functions have changed 
making the (relatively) old synaptics unusable?
