kernel version 2.6.31.5-0.1 on openSuSE 12.3

Hi,
I have installed openSuSE 12.3 on my system (want to run OFED-1.5.2 and MVAPICH2)
OpenSuSE 12.3 has 3.7.10.1. kernal version. OFED does not support this kernal version.
How i can install 2.6.31.5-0.1 kernal version on opensuse 12.3?
(i am new to Linux and step wise instructions will be of great help)

thanks in advance
