I suppose it does because it works perfectly when I put it in menu.lst file in GRUB config or specify it in GRUB before the kernel boots. >>> 3. have you read Documentation/svga.txt and Documentation/fb/{fbcon,vesafb}.txt ? >> No, I havent, yet. > > >>> And my comment is that your question (about video) would be better on the >>> linux-fbdev@vger.kernel.org mailing list.

It is not binary-only, I have to rebuild the driver in every kernel change. Regards, Piotr Hosowicz -- "Chcemy waszego dobra!" - powiedział lider socjaldemokratów.
