Ed,

I was hoping to find an "automated" solution.

Some way to execute the compile before X is started.
I am already detecting a kernel change and recompiles selected needed 
modules and reboots but this happens
by /etc/rc.d/rc.local. This is too late. X is already trying to start 
and /etc/rc.d/rc.local never gets executed as the machine locks.

This is for more than just one machine.

Thanks,

Jerry
