No problem, I use it like that all the time. This is from my kernel config:

pms*		at pckbc?		# PS/2 mouse for wsmouse
wsmouse*	at pms? mux 0

ums*	at uhub? port ? configuration ? interface ?
wsmouse*	at ums? mux 0

pseudo-device	wsmux		2

You may need to change "pms" depending on your laptop.

Then, in /etc/XF86Config, in the Pointer section:

	Protocol	"Wsmouse"
	Device		"/dev/wsmouse"

You can also get a serial mouse to work "at the same time" as the
others by using the "Xinput" XFree86 method.

Good luck,

P.S. I actually have one small problem with using a wheel mouse
together with a two-button only mouse. The options:

	ZAxisMapping	4 5
	Emulate3Buttons

does not seem to work both at the same time...
