Comment # 8 on bug 1114588 from Takashi Iwai

OK, then it's likely a relevant issue as the upstream bugzilla in comment 6.

The next thing to check: what happens if you boot with
psmouse.synaptics_intertouch=1 boot option?  Does the touchpad still work?
If yes, please give the dmesg output.

If the touchpad works with that option, try to boot with both
psmouse.synaptics_intertouch=1 and psmouse.noaux=1, and check the
suspend/resume.
(Also it's interesting to test without psmouse.noaux=1 option.)
