Does this work as expected with Mysql 4.0.x though?  

what about this paragraph from the link you gave ...

"If a DEFAULT value is specified for the first TIMESTAMP column in a table, it 
is not ignored. The default can be CURRENT_TIMESTAMP or a constant date and 
time value. 

DEFAULT NULL is the same as DEFAULT CURRENT_TIMESTAMP for the first TIMESTAMP 
column. For any other TIMESTAMP column, DEFAULT NULL is treated as DEFAULT 0."

I suppose we need to test this a bit.
