I face the same issue with a lenovo thinkpad t420. After suspending the
left mouse button does not work. Everything else works fine.
I tried your suggestions with uncommenting i2c_i801 and adding
"psmouse.synaptics_intertouch=0" to grub. First I tried uncommenting;
this did not work. Then I added "psmouse.." to grub and keep i2c_i801
uncommented; this did not work. After that I tried only addind
"psmouse.." to grub which also did not work. I also tried to delete and
add psmouse and i2c_i801 from kernel with modprobe. Also no changes.
Another strange thing is, if I run "xinput list" and choose the id of
"SynPS/2 Synaptics TouchPad" and run "xinput --test 11" I get the
following result after pressing left button (1) first and then right
button (3):
button press 1
button release 1
button press 3
button release 3
So it seems that the system is notified about it..
Here are some details about the system:

Finally one thing which works independently from both changes (i2c_i801 and
modifying grub) is to switch to another tty like pressing CTRL+ALT+F3 and
switching back with CTRL+ALT+F2. But I do not have any idea, what is loaded or
unloaded after doing this.
Let me know if you need more details..
