I remember this problem from ages ago, when I added a 2.6.8 kernel to my Sarge 
installs. When booting with the 2.6.8 kernel there was no mouse pointer. I 
had to modproble 2 modules, "mousedev" , and "psmouse" (without the double 
quotes). One of them got the mouse pointer to appear, but I couldn't move it, 
and loading the other module resolved the problem, and the mouse pointer 
could then be moved. It's worth a try, but your's may be a different problem.

If it does work, just add to /etc/modules on separate lines:
mousedev
psmouse
