Yep, it failed many times with a file not found error.  I have a copy of
/boot there but it is just a copy of sda.  In the past, I have had one
/boot and booted two different Gentoo OSs with no problem.

This is what I don't get, when I point the root=/dev/sda2, it should
point to that and load the fstab file there to mount the rest.  For some
reason, it goes back to sda even when told not to.

This is confusing me.  When grub is pointed to something, it should go
there and error out if it is not the correct one such as pointing to the
wrong partition.

This is weird.
