http://thalion.exotica.org.ukI wrote this site originally on my Amiga and the resolution is still set for 640x512 screens. No Java script or any other stuff, just a few plugins that you'll never miss.
My Amiga config is very similar to yours except I have a 25MHz A3640 and a DKB3128 RAM card. Loading & Compositing is VERY slow when compared to a modern PC browser but WTF do you expect?
I'm not 100% uptodate on AmigaOS but does having the latest / fastest datatypes help with Browser rendering speed? Perhaps ones designed for RTG cards?
