Raid array won't auto-assemble

I've moved over from Archlinux, where I had created a Raid5 array, to slackware64 13. After some problems with installation due to my own stupidity, I am STILL having problems with the Raid array. I can manually run mdadm -As to assemble it but it will not automatically assemble on boot.

Part of the problem is my complete unfamiliarity with slackware. I'm used to an rc.conf and mkinicpio.conf files that are used to add modules, daemons, scripts, etc to the boot. From what I can tell slack has mkinitrd.conf and rc.modules for loading stuff, but I have those configured for raid and it still won't scan the array on boot. rc.modules even has a line to add "/sbin/modprobe raid5" to the boot but there ISN'T EVEN A RAID5 module. I'm using the huge kernel so I guess it's built in. mdadm.conf is set up with the array information and I've tried scanning devices by partition (how I had it set up before) and by explicitly stating the drives.

Basically, how do I get mdadm to run --assemble --scan at boot? Do I have to make an rc.mdadm or is there some other file where I can state parameters for mdadm to run at boot?

So should I just make a script to run

/sbin/mdadm -As
/sbin/mount /dev/md0

and link to it in the rc.local file? Seems kind of hack-ish to me I figured it would naturally pick up the array so it could check it with the other disks.
