A working touchpad!

Ubuntu 14.10 Utopic Unicorn
Linux kernel 3.17.0
Toshiba Tecra W50-A

After months of waiting I now have fully functional touchpad on my laptop.  Work bought me a very new, relatively expensive notebook, which of course means it's taken the linux kernel some time to catch up with my hardware.  The touchpad was identified as a generic PS/2 device, and while I had basic functionality, niceties like scrolling -- nevermind palm detection -- were out of the question.

I had hoped that the 3.16 kernel shipping with Ubuntu 14.10 would do the job, so I upgraded even though I would have preferred to stick with the 14.04 LTS version on this machine.  No luck.  But the upgrade went rather painlessly, which emboldened me to try installing the latest stable version.  These instructions worked without a glitch, and as soon as it rebooted I knew it had worked!  (The mouse pointer responded subtly differently.)  Now I have a new device to configure.
