But isn't that exactly what's supposed to happen? If you don't have your
floppy drive inserted, you hardly need to have a /dev/fd0.

Did you always have to do that? I do. I can only attach my USB mouse (on an
Inspiron 2500 w/ 2.6.7) _after_ I get the Synaptics pad recognized. I'm
sure that's something to do with the ordering of the loading of various
modules, because I can get X to start up if I very carefully remove all the
modules, then modprobe psmouse, then start X, then connect the USB mouse.
I wonder it it would help to add mousedev to /etc/hotplug/blacklist and
modprobe it later...
w/ 2.4.27 I can't use the USB mouse at all.

(which will also insert hid and evdev, maybe others)
