If you or anyone else have additions to this document, let me know. It
waits desperately for more detailed explanations and restructuring in
many places.

I have no idea whether the Cyberblade i1 and 3d are the same. If your
device has the following PCI id it is the same:
        .vendor = 0x1023,
        .device = 0x9880,

The Cyberblade code is not working though. If it would work, you would
not even need to set CONFIG_VGABIOS to get something on the screen.
It might be as simple as adding a delay to the outp() function but I
have no idea. It is enabled in the newisys/khepri build. I added some 
debug output to the driver.

If you have some time, feel free to fix the cyberblade code. This would
be valuable for quite some AMD64 systems, including the Newisys 2100 and
Sun Fire V20z display.
