Andrei,
Tried to build a kernel image using the following.

basically i took every module from the i386-pc/*.mod directory and
attempted to add it. The image was too large so i went through the
module list and removed stuff that i was pretty sure i didnt need.
When i boot the image, i see nothing but the memdisk, i'm also in
that
same grub2 shell. I should see a (hd0) along with my (memdisk)
You need to include biosdisk into image (or in memory disk and load
explicitly from grub.cfg). PC BIOS offers alternative disk driver so
this is image-build-time option.

And "ls" in CLI shows me all disks. Of course you also need to manually
load suitable partition drivers to access partitions.
Alternative is to use grub-mkstandalone ... --modules=biosdisk.
May be we should add --disk-module option of grub-install to other high
level tools.
Oh, and $prefix in standalone image is set to (memdisk)/boot/grub,
which
means you need to put grub.cfg in /boot/grub if you want it to be
executed automatically; you use graft syntax for this
grub-mkstandalone ... /boot/grub/grub.cfg=/path/to/your/config/file
