Well, devices _always_ disappear.  In days of yore, devices got created
in /dev and stayed there.  Now udev creates them every time you boot.  I'm
assuming that the device isn't disappearing except at boot time - but
that's not 100% certain from your post.

I expect you're right.  You might try:

# sudo /etc/init.d/dbus restart

and see if hal finds it the next time it runs.  You should copy the output
of "lsmod" while the device is missing, and compare it to the output from
lsmod when the device is present, and see what modules are missing.
