My problem was caused by directly using /dev/psm0 in xorg.conf.
I applied your suggestions, switched to moused and now virtual
scrolling works.

I noticed a minor problem though.

Each touch of the vertical scroll area results in a small horizontal
scrolling step to the right.

This makes it impossible to just scroll vertically in Firefox if the
displayed page is wider than the browser window and lets scrolling
to the left take a little longer.

Looks like I will profit as well. I still prefer the touch stick for
moving the cursor, but virtual scrolling is great.
