Getting the synaptics touchpad working in Jaunty

Ubuntu bug 337935 describes a problem experienced by users of newer Apple laptops when installing or upgrading to Jaunty Jackalope.

A proper fix requires some kernel hacking, but the work around is relatively painless.
One need only add to /etc/modprobe.d/blacklist.conf the usbhid driver, and then add the bcm5974 on a line above usbhid in /etc/modules. This will prevent the usbhid driver from grabbing the synaptics touchpad before the proper bcm5974 driver has a chance.
