Xubuntu 7.04. I can do many websites that I browse regularly (Engadget, Gizmodo, Lifehacker) on my 350MHz iMac, from Firefox. With 466MHz it should be great! I have had problems with 7.10 so stay away, also when you partition, do it in drive setup: Make a OS 9 partition and leave the rest free space. When you go to partition in the Linux setup just make it take over free space. If internet is what you want to do, Linux is what you need!
