Yes, your screensaver must be GC-supported to support Snow Leopard.
This bit me recently too - I wasn't expecting it either. So much for
GC making our lives easier, eh? :)

On the bright side, you can make your bundle GC-supported, which means
it contains both retain/release and GC logic. This will at least buy
you 10.5 & 10.6 support in the same bundle, but I imagine you'll have
to compile a separate GC-unsupported version for 10.4, but I'm really
not sure. Hopefully someone else could comment on that.

But if I may, I thought I might mention OS 10.4 was released almost
0.5 decades ago. :)
