I don't know the 5520 so I can't talk from personal experience but I
believe the 5520 has a Synaptics trackpad so it (including the various
wheel and button emulation functionality) should be supported by
x11-drivers/xf86-input-synaptics and the various Synaptics management
utilities.

There are also typically physical microswitches under the trackpad -
these should trigger normal mouse button events independent of the
trackpad support.

The X.org codebase is common across BSD/Linux so behaviour elsewhere is
a reasonably good guide to behaviour on FreeBSD.
