The late '60s first "modern mouse" (a ball design driving
perpenducular axis) had 3 buttons. In fact, the inventor was
so ahead of his time, he also invented the 5-chord keyboard
so you could input any keystroke without having to use the
QWERTY keyboard (unless you were typing at full speed --
which you wouldn't be using the mouse at the same time).
[ SIDE NOTE: Imagine if he had established the 5-chord like
the 10-key numeric pad -- we wouldn't have all those varying
and non-standard gamepad controllers,. ;-]
The early '70s Xerox PARC Alto had 3 buttons.
And early '80s X-Window system begin with and still
_requires_ 3 buttons (even if you just emulate the 3rd button
with 2). ;->
More recent X-Window releases have supported 5 or 7 buttons.

I always scoffed in the early '90s when I plugged in a
Logitech 3-button to Linux and I instantly had full 3 button
support. It wasn't until Windows 98 before Microsoft started
including 3 button support without having to load additional

A 3-button mouse? You mean you've been using 2-button mice?

"Wheel" mice were easily adapted as 5-button mice. Button 2
(3rd button) is when the wheel is depressed (just like any
3-button mice). Button 3 and 4 (4th and 5th buttons) are
mapped as the up/down of the secondary Y axis (secondary to
the Y-axis in the ball/optical).
Most modern mice have native drivers in XFree86-4/Xorg-6.7
that can read variable rate and other, more "rich" feedback.

Intellimice will be recognized immediately in any modern
Linux distribution. Not only for X, but for console (e.g.,
gpm) as well.

Been using 3 button mice in Linux since I started in 1993. I
mapped buttons in X for a few 5 and 7 button digitizers
before any wheel mice ever came out.
The X-Window system has always had extremely flexible input
options. Especially since X is designed for
multiuser/multidevice (multiple input/output devices) on a
