::sigh:: naturally, I succeeded in answering my own question just
minutes after getting frustrated enough to send this e-mail.
Removing the "console=tty0,9600" from the kernel boot line fixed it
right up.

I'm working on integrating RHEL5 in our environment, and I've stuck on
the part where we configure the startup stuff (traditionally,
/etc/sysconfig/init) to do simple text-mode output so that our systems
on serial consoles print out the entire boot sequence after the kernel
boots.
Unfortunately, this doesn't appear to be working in RHEL5 anymore. I've
modified /etc/sysconfig/init and set BOOTUP=serial (this works on
RHEL3/RHEL4), and additionally set GRAPHICAL=no (this is a new option).
The kernel is booted with the following command line:
kernel /vmlinuz-2.6.18-1.2747.el5 ro root=LABEL=/1 selinux=0
console=ttyS0,9600 console=tty0,9600
This results in the kernel itself printing to the serial console, but
once 'rc' takes over, nothing goes out of ttyS0 until agetty is fired up
and the serial login prompt comes up.
Any ideas?
