Gosh, it seems the "old way" is a heckuva lot simpler than the

What advantage is gained doing all that extra work in the "second
way"?

The mouse movement is available not only as /dev/input/mice data, but also as /dev/input/event* interface (but the ruby-patched Xorg that can actually use that is beyond BLFS). The main advantage is consistency with PS/2 and USB setups. You run the "inputattach" program and forget that the mouse is a serial one.

Also, the kernel does some interpolation of mouse data, so the cursor moves more smoothly.
