If this were the case I would not even be able to boot because the other system
is a new drive...

The Ultra ATA PCI card has its own BIOS and it recognizes the hard drive (I'm
trying to follow your train of thought

The problem is getting the new drive (and card) recognized. You can't see the
device with fdisk. Remember if I take these lines I added in grub, the system
boots as normal but the new drive is not recognized. It's quite possible that I
didn't explain myself properly... The system is currently running here's another
list of the lspci -v command:
02:09.0 Unknown mass storage controller: Integrated Technology Express, Inc.

Here's the motherboard's IDE current (active setting) It's UltraATA-100:
believe this is the motherboard's IDE:

It doesn't look like it's an I/O conflict.
This is how my systems sees the card right now (with the following grub.conf
title Red Hat Enterprise Linux ES (2.4.21-20.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-20.EL ro root=LABEL=/
initrd /initrd-2.4.21-20.EL.img
>From what I've read, it's the kernel doesn't know that there's another IDE
driver, in this case the Ultra ATA card. To overcome this the following ide
definition must be passed to the kernel(ide2=0x2820,0x2816 ide2=autotune):
title Red Hat Enterprise Linux ES (2.4.21-20.EL)
root (hd0,0)
kernel /vmlinuz-2.4.21-20.EL ro root=LABEL=/ ide2=0x2820,0x2816
ide2=autotune
initrd /initrd-2.4.21-20.EL.img
When I reboot the new ide2 is recognized as well as the drive. It's only after
the kernel image is selected when the system has the kernel panic. Since I
haven't had a successful boot I can only give you an fdisk -l on the only ide
hardrive:

You will also notice my /proc/ide:
#ls /proc/ide
drivers hda hdc ide0 ide1 piix
There's no ide2 and ide1 is for /dev/hdc (primary and it's my cdrom)
# ll /dev/cdrom
lrwxrwxrwx 1 root root 8 Jun 15 06:24 /dev/cdrom -> /dev/hdc
The device should be /dev/hde.
I appreciate everyone's input.
