What's with the graphics

[bacterium <bacterium@home.com>]

Hello.

I have installed debian linux on my Quadra 840AV. I am using Penguin 18 and 
the 2.2.6 (I think) kernel. For some unknown reason, the scroll rate is 
really bad in linux mode and the bottom line is white and has parts of 
previous lines on it.

Please help.
