kernel | dmraid question

I'm currently working on a sata 3G bios raid installation using dmraid. I'm at the kernel section where I'm a bit stumped. The guide to install on a bios raid tells me that I need an initrd to boot ... or something of the sort. I've manually compiled my kernel (no initrd) and I'm using 'genkernel --dmraid all' to build my generic kernel as a fallback if you will incase my prebuilt kernel doesn't work out. Now can I use my initrd I get from genkernel on my manually built kernel so that I can use that?

FcukThisGame,

dmraid provides 3rd party kernel modules so you cannot include dmraid support in the kernel bzImage file.
If your root is on a dmraid volume, you need to load the dmraid modules to mount root. This is a problem if they are stored on the root volume itself. The initrd is a fake root filesystem used (among other things) to hold third party modules needed to mount the real root filesystem. Its normally a compressed ext2 filesystem loaded by grun and mounted on /dev/ram0.

Might want to look at swraid devs just masked dmraid and apparently it is going to be dropped from portage.
