Yes, it has the fixes already. And both errata kernels for RHL 7.3
(2.4.18-) also have the fixes.

No, not strictly needed in that case.

The PERC3 series cards *do* have a PCI bridge on them. :-) So no you can't
use them on 7.2 without upgrading the kernel. Kernel 2.4.9-34 has the fixes
also, so you can install with just one PERC3 card then upgrade the kernel to
-34 immediately, and then add the other PERC3 cards.

It's kind of confusing, but essentially it looks at 'uname -r' for a match
on its internal list, and if no match, then use the DKS feature which
requires source. Even if the module already exists because you built and
copied it separately, since it's not known to the 'dellomsa-drivers' package
already, it'll try to use DKS. There's no "does this module already exist
in /lib/modules/..." test in the current implementation.

That wasn't intended, so there's no easy way to do this short of unpackaging
the dellomsa-drivers RPM (including extracting the scripts) and repackaging
it with the changes you want yourself.
I'll create an RFE for the OMSA team to see if they can add such a test into
