i found this address: http://www.minion.de/
which i found on this bbs to seem some what helpful. it seems to describe my experience well, the black frozen screen wiwth ascii garbage that is. i followed its instructions to add the NvAGP option and removed AGPGART from the the kernel but experienced no success.
i've really been breaking my back over this one for a month now more or less. if someone can offer some ensight it would be greatly apreciated.
