My copy of grub is 33K - does it fit?

If you can get grub loading from the SPL, that's excellent.
To get grub to allow you to boot a kernel from the DiskOnChip, you have to
build the DiskOnChip support into grub's disk drivers. For this you have to
replace the rawread() routine in shared_src/disk_io.c
The code in my doc2000.c and nftl.c ought to be enough to help you add this
support.
