intel motherboard megasr source code


Does anybody know were I can download a copy of megasr.c and megasr.h

I am trying to get SLES11 rc1 to load. SLES 10 runs fine on the same motherboard. However the megasr.ko that I ahve for sles10 will not insmod !! so I need to compile the same for sles11

Any pointers would be welcome !!
