I update these by hand/script. The mkinitrd isn't too painful. I have
it on a machine at the lab (which happens to be off now, and I am at
home). Will put that out in the morning. The grub update is fairly simple.

Hmmm... I normally recommend avoiding their spec file unless you want to
use only their kernel and do minor tweaks from there.
This said, I really recommend using
to generate the kernel/modules RPM and SRPM. Then the grub update and
the mkinitrd can be scripted. If you are daring, you can include those
scripts in the %post sections of the generated spec file (the make
binrpm-pkg will generate a spec file for you).

I'll be in the office tomorrow with the machines, I can send you the
exact mkinitrd line. Bug me offline if you have a baseline kernel you
want to get started with and we can walk our way through this.
