I collected a couple of articles which are of great help with determining a fair share split between startup founders. Here they are:
Splitting the Pie: Founding Team Equity Splits - interesting suggestion about dynamic split here
Startup Founders: Should You Divide Equity Equally? together with comments
The Founders' Pie Calculator - great plan for fair split
EQUITY: Dividing the Pie

[Update] Here is another link where people discuss fair equity share (you'll have to register to read that).
