I'm not sure I understand this, but here goes.

1. I rpm'd a new kernel for FC3, 2.6.11-1.14_FC3. So, /lib/modules now
contains two directories, this one, and the old one 2.6.0-1.667. I'm not
sure what I'm doing, but I guess the new directory is used instead of
the old. GRUB now says I can boot either.

I don't see anything that relates to Serial ATA drives within either
subdirectories.

man for mkinitrd says it builds a ram module for RAID devices as well as
other things. I think that's what I want, but it isn't obvious to me
what's going on.

Here's what I mean.

If I install FC3 on a S-ATA drive, how do I run mkinitrd, since the
entire Linux system (except 1st part of GRUB) is hanging someplace off
the root filesystem on the very drive I'm trying to get to. 

In fact, how do the installation CDs even install on the drive?

Hopefully, you see my confusion.
