I don't use vesafb for anything other than the graphical console with large number of columns and rows, so it shouldn't affect me. I just needed a quick hack for a fix since I got a new MP system with lots 'o ram and no penguins :( It's all good now though.. -Walt ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event.
