I've noticed a bug with it, but haven't had time to investigate more fully, infact it might not be a kernel bug, but I suspect that it is.  I don't usually use the framebuffer, (I prefer the standard text mode).

On a standard Slackware 8.1 install, (kernel 2.4.18), on a machine with an ATI graphics card, and with the framebuffer enabled, if you type clear, then fill the screen with text so that it scrolls, (e.g. do a find /), the top four lines where the penguin used to be do not scroll, they just keep the text that is originally put there.  If you press shift-pageup, and then shift-pagedown, it fixes it.

If anybody has got the time to look in to this, I'll post more details.

John.
