Can anyone help me with a problem I am having with the savagefb patch ?

I have one of those small-format motherboards with a VIA EDEN CPU. The graphics chipset is described in the manual as "4X AGP S3 Savage4 3D and Savage 2000 2D engines integrated in VT8606 supporting up to 32MB of shared memory".

I applied the patch from DirectFB-0.9.19 onto linux version 2.4.21-rc2

When I compile my kernel with vesafb, everything works perfectly.

When I compile my kernel with savagefb, it spits the following during bootup:

divide error: 0000

I am now resorting to RTFS but I am hoping that someone who is more familiar with the way this driver works could give me a hint or two.

The reason I want to get this work is that I want to be able to switch to 640x480 to play a video full screen and then swap back to 1024x768 when the video is finished. I can't do that with vesafb.
