Welcome back sicky 
Hopes it's ok to ask some OS4 Classic questions here....
Do you need OS4.0 Classic installed first before you can install OS4.1 Classic?
As far as I know it's a standalone release.
Will OS4.1 Classic work with GFX cards like the Cybervision 64 and Picasso IV or must you have the Radeon card?
You certainly need a Radeon card if you want to have fun with compositing. As for older cards, I can't say, only having tested it on BVision, but I can't see why any of the above legacy cards wouldn't work provided they had working P96 drivers to begin with. Perhaps someone with one of those cards can clarify.
