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:
Option "AllowEmptyInput" "off"
... 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.
