i have 2 radeon 9800 pros -- one in my g5 + and one in my MDD --
one of them is flashed, the other is a REAL mac edition radeon 9800 pro
i also own a sawtooth which ive used it with many times, so i think i know what im talking about
unfortunately this card does not support proper 2D accell in mac os 9
it would be amazing to get someone to hack the 2D accell to work for any graphics card powered by the R300 series GPU chips
but this has not yet been accomplished by anyone as far as i know
the card is so fast that its almost usable but if you are doing any real work on the os
you will soon get frustrated with the screen-rollup-refresh that occurs when 2d Accell is not enabled/supported
so it will "work" for mac os9 but not "work well" - untill the r300 series driver support is achieved for mac os 9 these cards
are only really usefull for osx panther, tiger, leopard on G4's + G5s.
the radeon pro is AGP 8x yes but it is downward compatible with 4x + more importantly 2x
so it works on the sawtooth without any mods or pins taped
this info has been available for some time here:
