Sudheer,

You need to download the SystemAce patch and apply it to the 2.6.17.1 
Kernel.  The patch can be downloaded from: 
http://www.cs.york.ac.uk/rtslab/demos/amos/xupv2pro/patches/linuxppc-2.6.17.1-sysace-1.2.patch

Save the patch to the root of the Kernel sources and run the following 
command:
patch -p1 < linuxppc-2.6.17.1-sysace-1.2.patch
