It should be a complete drop-in replacement, except for people who
really, really, like the old line-based "pixel" scrolling. And I think
it's already there, sans bugs like what you are experiencing.

Hmm, that sounds like a bug. Could you please run the following code:
(progn (read-event) (message "Device: %s" last-event-device))
and show what is printed once you turn your mouse wheel?

Try playing with pixel-scroll-precision-interpolation-total-time, and
pixel-scroll-precision-interpolation-between-scroll. I agree those
options should be easier to use, and I will work on them at some point.

Those options are under the "mouse" group, but I won't object to moving
them into their own group.
Thanks.
