Alps driver for E6330 that supports two-finger tap for right click?

I'm using a Dell E6330 and would like to use the two-finger tap for right click as another user describes for a different Dell system here: http://en.community.dell.com/support-forums/laptop/f/3518/t/19476719.aspx .

However, the driver set listed there doesn't offer the same functionality on my 6330 so I'm back to using the Dell-provided driver. Is there a driver (from Dell or otherwise) that offers this for the Alps touchpad on this system?

As an aside, the Alps touchpad is really inferior to the Synaptics one shipping on the entry-level Inspirons (like the 14R-5437). If it's weren't for the superiority of the Latitude keyboard, I'd think the Inspiron were the better system.
