It's the video system.  The 486 is probably using some vga or svga card.
Such cards have a "text" mode and a "graphics" mode.  The Macs essentially
just have the latter.

Basically, the MacBSD display speed is slow because we have to draw the
character whereas the PC's just have to say, I want character "x."

Accelerated video cards might very well help, but only if we can make
use of the accelerated features.  Right now, we can't :-(
