I don't like the idea of making memdisk filesystem-dependant.  But adding
a more size-oriented filesystem to GRUB would be nice of course.

How about tar?  If we use an existing fs, we get the user tools for free.

Btw, note that the filesystem is embedded inside the LZO compressed block,
not just concatenated.  This should get rid of most of that 0x00 padding
