Make sure your not overclocking your CPU ,during the process of
compiling a kernel you will
be very more likley to experience processor errors otherwise.

Suggest try and compile a kernel with only standard features,
A few tips in the src/linux/Makefile

change the minor number version of the kernel (ie from .5 to .6 or
something ) 
so you can have 2 seperate sets of modules
and then after rebuilding the kernel do
make modules 
make modules_install

You need to move or copy the new kernel from the
src/linux/arch/i386/boot/compressed 
directory to the /boot directory , give it a unique name
and i suggst adding a second boot to your lilo.conf file
so you can have the old and new versions fo the kernel you built
available at boot time
ie 
see my lilo.conf file - i have 4 versions available to use at boot time

If things gett to stuffed up just use gnorpm to get rid of the kernel
source files
put in your cdrom of redhat and reinstall the linux kernel development
and 
source RPM's again ie cd the the RPM's and use 
rpm -i 
followed by the rpm's you want to reinstall
if it complains use fource ie 
rpm -i -f
