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!
