If it was by a simple remounting as ext4, then the file on-disk is still using the ext3-format bitmap, and not the ext4-style extents. It is this on-disk extent support which GRUB cannot handle at this time, and what the proposed patch accomplishes. When remounting an ext3 filesystem as ext4, only newly-created files use this extent support.

The development of Grub legacy stopped before ext4 was mature. There are unofficial patches to support ext4 on Grub legacy; the discussion on Debian bug #511121 has a pointer to two patches (one of which is in some versions of Ubuntu). Grub2 (1.9x, more precisely since 1.97) supports ext2, ext3 and ext4, with the same module (ext2.mod).

GRUB 2 includes support for ext4 boot partitions. This is helpful because it prevents you from having two different file systems running for the boot partition and everything else. Standardizing on one file system simplifies things, and keeps you from splitting a single hard drive into multiple partitions.
