Comment 75 for bug 990260

I have a MSI CR640 laptop with Sentelic touchpad. It worked well without any scrolling support before 3.4. After upgrading to 3.4, the cursor became jumpy and any scrolling still wasn't working. After applying v3 patch (and modifying one line as said in later comment) from this thread, the cursor doesn't jump, two-finger vertical scrolling partially works (it usually scrolls but when i put finger up, it returns to original position) and edge scrolling doesn't work. I tried changing hscroll attribute in /sys/devices/platform/i8042/serio2, but it didn't do anything.
