Which Shibby Tomato firmware for E1000 v1?

According to http://tomato.groov.pl/?page_id=69 , the Linksys E1000 v1 is supported. It has 4MB of flash RAM with the MIPSR2 CPU. It says to use K26.

I'm looking for which firmware will give me an OpenVPN server. Does this firmware have to be under 4MB?
I see that the 124 version ( http://tomato.groov.pl/download/K26/build5x-124-EN/tomato-K26-1.28.RT-MIPSR2-124-MiniVPN.trx ) is 4.0MB.

Which is the most recent Shibby VPN firmware that I could use?

Thanks!
