Rebuilding kernel-source for NVIDIA drivers help!

Here is a quick response that may get you going.

Fine so far -- but you need to also manually edit the config files to
remove the 4K stacks default value of y, you should set them to:
# CONFIG_4KSTACKS is not set

If you do not use the minion.de patch, you MUST set register parameters
off as well:
# CONFIG_REGPARM is not set

Suffix created to identify that this kernel was a custom built kernel,
you can change the behavior to be whatever you want in the spec... but
you should leave something on the end to know it is not the default
kernel (it makes no difference to its capabilities, etc...)

%define release %(R="$Revision: 1.327 $"; RR="${R##: }"; echo
${RR%%?})%{rhbsys}

On the end you see, rhbsys, which in the previous statement is set to
your username by the 'whoami' command.

You must run that after you reboot to the target kernel, or specify that
you are not running the target.
--kernel-name=2.6.5-1.327.root

You may still need to specify the kernel-source-path, but the above is
the real issue.
