CodeIgniter with php5 - CI-generated 404 Error

[eluser]Eric Cope[/eluser]
So I did some googling on the topic of ORIG_PATH_INFO. Apparently, there is a bug in PHP when run in CGI mode regarding what is returned in ORIG_PATH_INFO.

My server runs php4 with the server API as apache.
My server runs php5 with the server API as cgi. <- smoking gun???

Derek, can you confirm that the dreamhost problem you are having is running in cgi mode?

This bug report is for php4, but I am not sure if it applies to php5 as well...
