Ah wait a second - I think I know what's happening here. Several months
ago I found a couple of bugs in fs/iso9660/* related to loading files
from CD. I seem to recall:
i) The filenames all had to be in capital letters
ii) Sometimes I had to put an extra . at the end
I found these bugs by stepping through iso9660_opendir() under gdb. So
that is likely what's happening here - OpenBIOS is unable to locate the
file from the filesystem at boot time.

Yeah because while the grubfs iso9660 implementation doesn't have the
case-sensitivity/period bugs, unfortunately the grub API doesn't provide
a function to list files within a directory.
If you could provide a patch to fix these bugs in fs/iso9660/* then I
would definitely apply it :)
ATB,
Mark.
