I did some searching and I found an XF86Config-4 file for a laptop using the CyberBlade video, here is the video "device" section:
(snip)...
Section "Device"
Identifier "vesadevice"
Driver "vesa"
# If you disable shadowfb, you find what it really means to have no
# acceleration. So don't do it.
Option "shadowfb"
EndSection
(snip)...

Notice two things:
Driver "vesa"
Option "shadowfb"
you might want to starup with:

knoppix xmodule=vesa

and see how things work, if that seems OK you should be fine running like that, if you need to use the "shadowfb" option you may need to startup with:


knoppix 2
and then edit or copy over a fixed XF86Config-4 file then start X using:

su knoppix
startx

HTH
