Is the driver from via any help? I have 2 different versions on my computer.

http://www.viaarena.com/Driver/k8m890xf40069-kernel-src_20060620.tgz
This driver package provides the kernel source code for the Chrome9 
K8M890 display driver. Follow the "VIA S3 UniChrome Linux Display Driver 
Source Code Compiling Instructions" to compile the source code for 
different kernel versions. This driver supports the 2D (X-Win, TV-Out, 
TVUtility) feature only.


http://www.viaarena.com/Driver/k8m800_890-p4m890xf41068-kernel-src_20060707.tgz
This package provides the kernel source code for the UniChrome Pro 
K8M800/P4M890 and Chrome9 IGP K8M890CE Linux display driver. Follow the 
"VIA S3 UniChrome Linux Display Driver Source Code Compiling 
Instructions" to compile the source code for different kernel versions. 
This driver supports the following features: 2D (X-Win, TV-Out,
TVUtility); Video (HW Overlay Accelerator). It also supports DDMPEG (VMI 
- VIA HW Mpeg Accelerator) for the K8M800 only.

Both of them are for fedora type systems and I havent figured out how to 
hack it yet.
