What you are searching may be in the rom of the card. Look for ftp://ftp.poupinou.org/riva/riva_edid.tar.gz This was done in fact for another purpose, but may be helpfull for your problem. For the PPC case, I believe this can be done via openfirmware. This may work for nv up to 15. Not sure for newer. Cheers, -- Ducrot Bruno -- Which is worse: ignorance or apathy? -- Don't know.
