RedHat support booting 32-bit & 64-bit kernels from single installation?
 

Greetings,
Is it possible to install either 32-bit or 64-bit RHEL, and
then configure it to boot the other kernel? For example,
can I install RHEL5 64-bit, and then boot a 32-bit kernel?
I have a customer who has a requirement to boot either kernel.
I'm trying to determine if this is possible, or will I have to
perform a dual-boot installation for each release. I suspect
it's the latter.

Thanks,
- Bill
