Re: modutils for both redhat kernels and 2.5.x

[Bill Beebe]

I too run with Red Hat 8.0. I had to build 2.5.49-ac1 with module loading
disabled (I also got some excellent help/clues from Rusty Lynch when it
wouldn't link). Because of that I've got a rather large kernel (~1.6meg)
sitting in /boot right now. I can run (in X even) with 2.5.49-ac1, but I
wouldn't want to do that for long periods of time until I better understand
what's going on with the kernel. And brother, am I ever confused. BTW, just to
fan the flames even further, I built 49-ac1 with gcc 3.2.1.
