Changing the below line in /etc/modprobe.conf alias scsi_hostadapter1 megaraid -> alias scsi_hostadapter1 megaraid_mbox allows mkinitrd to create an image with the 'new' megaraid drivers. I haven't tested the result, but maybe some can give it a try on a non-critical system. Remember to change it back to the original line when you want to boot a kernel with a megaraid.ko driver. CAREFULL NOT TESTED, this is just a suggestion. Willem.
