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. 
        
Thanks,
Frank
