I have a Gentoo on a T30 and this is what I did to get my Ultranav USB mouse 
and up and running.  This got all the Ultrav stuff working (stick, 3 stick 
buttons, tap on the pad, 2 pad buttons) and also allows the mouse to be 
plugged in or out at any time.

I did not emerge x11-misc/synaptics as I found that synaptics_drv.o was 
already present in /usr/X11R6/lib/modules/input.  From inspecting the 
ebuilds, it looks like this file gets automatically downloaded and installed 
from http://w1.894.telia.com/~u89404340/touchpad/files/ when x11-base is 
emerged.  The binary is exactly the same.  I did not have to explicitly add 
this module into my XF86Config file for XFree to load it.

I also emerged the hotplug stuff.


Relevant kernel config:

CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_EVDEV=m
CONFIG_INPUT_MOUSE=y
CONFIG_MOUSE_PS2=m

CONFIG_USB=m
CONFIG_USB_DEVICEFS=y
CONFIG_USB_EHCI_HCD=m
CONFIG_USB_OHCI_HCD=m
CONFIG_USB_UHCI_HCD=m
CONFIG_USB_HID=m
CONFIG_USB_HIDINPUT=y


kernel boot options:

Ever since linux-2.6.2 I have had to use i8042.nomux, otherwise XFree86 
doesn't recognize the ultranav properly.  This wasn't necessary for 2.6.[01].  
(I would be delighted if someone could enlighten me!)


/etc/modules.autoload.d/kernel-2.6:

This is just what worked for me.  YMMV.  Good luck!
