[edit] Kernel Config and Working hardware

Linux Kernel Configuration: 
 Power management options (ACPI, APM)  --->
  CPU Frequency scaling  --->
   <*> Intel SpeedStep on 440BX/ZX/MX chipsets (SMI interface)
  • Video: Supported resolutions (laptop dependent): 1024x768, 1400x1050.

[edit] Problems and Solutions

[edit] Video: X.Org

DRI/GLX support requires the following options in xorg.conf Device section:

File: xorg.conf 
 Option "BusType" "PCI"
 Option "DmaMode" "None"

or use the real fix for DRI/AIGLX support

File: xorg.conf 
 Option "AGPSize" "8"
 Option "AGPMode" "2"

The real problem is that the default AGPSize for the savage driver is 16MB. While the actual video RAM on the savage card is 8MB. That is why switching to PCI and no DMA aka no AGP works.

[edit] Video: Framebuffer

The Savage driver may break the framebuffer. Use the VESA framebuffer driver instead.

Linux Kernel Configuration:

Device Drivers -> Graphics -> 

<*> Support for frame buffer devices
<*>   VESA VGA graphics support
        VESA driver type (vesafb-tng)  --->
< > S3 Savage support
