Here are the patches I use for the splitting. They work well. The methods employed in Red Hat ES are far better and I am surprised no one has simply integrated those patches into the kernel which are 4GB / 4GB kernel/user.

So, the patch would now look like this:
can we please state something what the 3G_OPT is suppsoed to do? Is this
"optimzed for 1GB Real RAM"? Should this be something like "2.5G" instead?
