It uses libhal, I believe to find input devices and I was finally able to work around the problem by configuring an manually recreated xorg.conf file with the magic option:
Section "ServerFlags" Option "AllowEmptyInput" "off" EndSection
... and then making sure that the kbd and mouse input drivers were installed. There is definitely something wrong though if sometime between 2;6.33-rc4 and 2.6.33 we've made some incompatible sysfs change that breaks hal on Ubuntu 9.10 (which is still the latest Ubuntu community release), such that people can't test 2.6.33 kernels using it --- at least not easily.
See Linus's complaints over the nouveau driver; it's the same principle; something is really broken.
