Abraham,

When I build kernels for LTSP workstations, I NEVER use redhat kernel
sources.  they apply many many patches to their kernels that the
workstations just don't need.

If you want to build your own kernels, I suggest you go to ftp.kernel.org
and grab yourself a nice fresh set of kernel sources and have fun with that.
