The installer recognizes my Number Nine card as an "Imagine 128" when it is, in fact, a Revolution 3d. This results in the GUI installer failing. Trying text mode also does not work, as it again auto-recognizes the card as an Imagine 128 and the X server will not start. The Rev3d does use the Imagine 128 chipset, but it seems there are some differences. I noticed a reference to it thinking the card was PCI, when it is in fact AGP. I also have a copy of RedHat 6.0 which I got from LSL, and the manual video card selection does have an option there for the "Revolution3d AGP with 4-8 Meg SGRAM" -- that worked fine, and I was able to install Red Hat 6.0 on the machine. However, since the 6.1 update seems to want to re-probe the card, I cannot install 6.1 fresh or as an upgrade.
You can run Xconfigurator after installation with the "--expert" option which will allow you to configure the card manually. Please send the PCI vendor ID and device ID and we will make sure this is in the pcitable.
Closing bug due to lack of activity.
