I have the same problem with Ubuntu 16.04 on a Thinkpad X260. I have
disabled the touchpad and only use the trackpoint but the PS/2 interrupt
is still by far the most frequent, in the hundreds of ms.

Bryce, it seems that the trouble still exists.
I use Ubuntu 14.04 x64 version. PowerTop indicates that while I wave
with the cursor using a trackpoint, the wakeups caused by PS/2 Touchpad

I'm reopening the bug. I can reproduce it on natty on my netbook.
Fwiw, I found that I could resolve it by doing:
echo 40 /sys/module/psmouse/parameters/rate

I can confirm this on Thinkpad T400 (Kubuntu 9.04 KDE 4.3), I left the
computer on idling with powertop for the night and over 85% of wakeups
were caused by the touchpad (trackpoint enabled in bios). I would be
happy if the wakeups would *only* skyrocket during actual touchpad use.

I agree, it seems very unlikely that all laptop touchpads have hard-
wired polling frequency that not even the best linus hacker could
override. Is this really the case? Can we get some more explanation on
the issue, and maybe some confirmation that it is the same on Windows?

I've tried two workaround and in this way I made it a little better.
1) Adding some boot option in grub's menu.lst file: i8042.nomux i8042.reset
i8042.noloop
er.
2) adding the following lines to my /etc/rc.local:

I found the site: http://web.telia.com/~u89404340/touchpad/synaptics/
