Errata kernels 2.4.9-{6,7,12,13,21} had problems specifically with the
aacraid driver, which have been resolved in the 2.4.9-31 errata kernel.  If
your colleague tried using those kernels, he may have experienced problems.
These are documented on in the aacraid section.

That should work fine.

Possibly.  Red Hat Network 'up2date' application is your friend here.  It
(by default) won't upgrade your kernel, but it will upgrade all the other
apps on which the kernel may be dependent (typically modutils and/or
mkinitrd need to be updated).

Indeed, caution is always warrented.  In that case I strongly recommend you
purchase a support contract, either from Dell (Gold or higher) Premier
Services, or from Red Hat directly.  They can assist you personally in the
event something doesn't work properly in your upgrade.
