So we are at the beginning. You have a partition table on the device, I
don't.

Anyway, I found it. It is buried in the filesystem modules of grub in
the mount hook. It checks for
| ((current_drive & 0x80) || (current_slice != 0))
|    && (current_slice != PC_SLICE_TYPE_EXT2FS)
|    && (current_slice != PC_SLICE_TYPE_LINUX_RAID)
|    && (! IS_PC_SLICE_TYPE_BSD_WITH_FS (current_slice, FS_EXT2FS))
|    && (! IS_PC_SLICE_TYPE_BSD_WITH_FS (current_slice, FS_OTHER))

Which reads as:
- If device is a harddisk,
- or it is a slice with none matching type,
then abort.

It simply refuses to find filesystems on the whole disk. If I remove the
current_disk check it is able to find the filesystem.
