Also since you had no problem with the mouse in 2.6 do you want to try and resolve the modem driver problem instead? What modem are you using? If it's a winmodem some of those can be difficult to get working-as you've discovered.
Have you checked this site? : http://walbran.org/sean/linux/linmodem-howto.html
Hope this is of some help.
Had the same problem, solved it by changing protocol=auto to protocol=IMPS/2 in /etc/X11/XF86config-4:

Code:
Section "InputDevice"
 Identifier  "PS/2 Mouse"
 Driver      "mouse"
# modified by CrashedAgain for wheelmouse support with 2.6.6 kernel
 Option      "Protocol" "IMPS/2"
        Option          "ZAxisMapping"          "4 5"
 Option      "Device" "/dev/psaux"
 Option      "Emulate3Buttons" "true"
 Option      "Emulate3Timeout" "70"
 Option     "SendCoreEvents"  "true"
