I am using the Xfree86 version 4.3 with knoppix to install mythtv
(knoppmyth). I am having trouble with using my nVidia Geforce 4000 mx
pci card. Assuming that is the hangup can anyone help me fix this? 

specs
Intel 2.0 ghz
onboard s3 savage 32 mb video memory
512 mb ram

anymore specs needed I will give any that I know how to get

thanks in advance
