    I had a similar problem on a Dell PE600SC and Red Hat v9.

    In order for the Dell CERC (megaraid) device to be /dev/sda, I
    had to set the an option in the CMOS;

      Setup CMOS Hard-Disk Drive Sequence

      1. System BIOS boot devices
      2. Slot3: CERC ATA-100/4ch (bus 00 dev 05)
      3. Slot5: 3ware Storage Controller

    Moving the cards around and setting the above options did not make a
    difference to what the POST saw. Linux, however, did notice a
    difference when I configured the above CMOS options. By default, the
    3ware card was being seen before the Megaraid by Linux.
