More than 4GB SGA on CentOS 5.4 SMP 32 bit

How to increase Oracle SGA more than 4GB on CentOS 5.4 SMP Kernel 32 bit ?

Situation :-
Oracle 11.1 release
CentOS 5.4 32 bit
Linux - 2.6.18-164.6.1.el5PAE #1 SMP Tue Nov 3 16:55:59 EST 2009 i686 i686 i386 GNU/Linux
RAM - 16 GB
Current ORACLE SGA - 4GB

After lot of research in google, I learned that above mentioned Kernel doesn't have Hugemem.
And it says still it can support up to 16GB in good performance using its PAE.
Most of the blogs and even oracle sites describing for VLM using Hugemem only.

Please let me know the steps to increase SGA in this scenario.
