Well, on 030 it must be slow but it works ok with 68060 Mediator+Voodoo. The bus is not used more, so it's a CPU issue when converting bitmaps. Every time this comes up someone mentions Mac. There's n+1 reasons why that is not feasible, but the most notable are obtaining a Mac-version (even OS), and the fact that running a Mac emulator (especially for software that exists natively) is quite irritating, more resources are used and so on. SC2k even uses AmigaOS for many interface components which is nice.
