Have you tested without X or gpm running? When I upgraded to 2.4.22 I noticed some issues when X tried to open /dev/input/mice before mousedev was loaded.
note 2: lsmod while running 2.4.18 shows
input 3456 0 [keybdev mousedev hid]
lsmod while running 2.4.22 shows
input 3456 0 [mousedev]
I presume from this that for some reason hid is not using input, but I
can't figure out why!
That's strage. I don't know if it is supposed to be or not, as I linked most of the USB subsystem (including HID) into my kernel rather than building them as modules.
Do you get a USB event when you connect your mouse? You should see something like the following in /var/log/messages:
Sep 11 10:37:55 localhost kernel: hub.c: new USB device 00:1d.0-1, assigned address 13 Sep 11 10:37:55 localhost kernel: input: USB HID v1.10 Mouse [Microsoft Microsoft USB Mouse] on usb1:13.0
