Weird... shouldn't have any affect on your keyboard...I'm typing on my laptop now!  Can you grep(1) your kernel messages for 'atkbd' and grep the Xorg log for '\(keyboard\|kbd\)'?

Yeah I wanna say that's because xf86-input-synaptics is talking to /dev/psm0 instead of /dev/sysmouse, but that doesn't sound right.  Anyway that's what I'm looking at now - the devd patch to x11-servers/xorg-server, and next is x11-drivers/xf86-input-synaptics.  If you're handy with code you could probably find the code in xf86-input-synaptics that balks at the Synaptics device.  My goal is having the user install these two packages on a touchpad laptop and have it just DTRT and correctly load the Synaptics driver.
