I turned it into a module, but the module may have been auto-loaded.  I
didn't check.

I don't think this is the issue.  The rescue disk brings up all of the
drives, including some LVM drives on the mapper device, which are built
on top of RAID-1 pairs.  Although in a boot w.o. the rescue disk, the
kernel recognizes the root filesystem when I spec it with /dev/sda4 in
grub.conf, this recognitions seems to be lost later in the boot process.

There may be some conflicts.  /dev/hda1 is a VMware partition, which
becomes /dev/sda1 in newer kernels.  /dev/sda1 is also a SATA partition
which is part of a RAID-1 array.  The Linux RAID-1 and LVM stuff seem to
pretty much take care of themselves, as long as the RAID and
device-mapper drivers are available in the kernel or as modules, and
this seems tangential to the problem.
