Hi Christopher,

I can confirm that upgrading the bios to A15 improves the situation a
lot.

Two finger scrolling is now usable, and the cursor no longer jumps
around when placing a second finger on the touchpad as described in the
original bug report.

I think that this bug can be closed.

            /Niels
