Somebody asked me to post a copy of my grub configuration, so
here it is:

------------------------------8<------------------------------
splashimage= (hd0,0)/boot/grub/splash.xpm.gz
serial --unit=0 --speed=57600 --parity=no --stop=1
terminal --timeout=5 console serial
default=0
timeout=5
title /boot/vmlinuz-2.4.18-comtrol-dm-ats (VGA)
 root (hd0,0)
 kernel /boot/vmlinuz-2.4.18-comtrol-dm-ats vga=0x303 root=/dev/hdd1 console=ttyS0,57600n8 console=tty0
title /boot/vmlinuz-2.4.18-comtrol-dm-ats (serial)
 root (hd0,0)

I use a version of Grub with the VGA16 splashimage support.
The VGA16 patches break serial console support.  If you want to
use VGA16 splash images and serial consoles at the same time,
you neeed to get a patch to apply on top of the VGA16 patch.
The vga16 and serial patche are available from RH (via
bugzilla), from the Grub mailint list archive, or from

 ftp://ftp.visi.com/users/grante/grub/   (patches against 0.91, IIRC)
