I read that has already been done. Has anyone given it a try?

I bought an ATI FireGL X3 on Ebay for about $20 CAD to do so.

Else than not being able to boot OS 9, would there be any other problem with using it on a 2001 QS? Will the screen show up only after booting?

If anyone has anything to share about their experiences with this, please tell me.

Thanks
