The easiest thing is to remove the 5300 and leave the 3200 in it.  Then:

  1.  Boot off the CD in rescue mode
  2.  "chroot /mnt/sysimage"
  3.  Edit /etc/modules.conf (or /etc/modprobe.conf on FC2)
  4.  Change the "alias scsi_hostadapter" line to use the 3200 driver
  5.  "cd /boot"
  6.  Make a new initrd image.  Use the "-f -v" options to make sure
      the right drivers are loaded.
  7.  If using lilo, rerun "/sbin/lilo"
  8.  "exit" twice (one to get out of the chroot, one to reboot)

Voila!
