Problems installing on G5 with multiple boots

[squishyray]

Hello:

I'm trying to install Gentoo 64 bit onto a G5 that already has OS X and YDL. I've done a stage 1 installation and got everything built. The kernel is compiled with support for ext3, SCSI, and IDE all built-in, not as loadable modules.

I added an entry into the yaboot.conf used by YDL pointing to my gentoo partition and ran ybin. The gentoo selection shows up when yaboot is loaded.

However when it attempts to boot the gentoo kernel I get the following error:
Unable to mount root fs on unknown-block(8,6).

Others who have encountered this problem were found to have used modules for require kernel components. Attached below is a subset of my config file where I pulled out all of the symbols containing EXT3, IDE, and SCSI showing which components were built into the kernel.

Also included below is a copy of my partition table and my yaboot.conf.

If anyone sees anything I left out please let me know. I've tried for a good while to get this to work and have run out of ideas.

Thanks,
SquishyRay
