OK, Orit (Cc'd) did some research - this is a booting
while still in grub, size probably does not get much less than that.
windows is said to be much more aggressive in allocating memory.

 start offset: 9600673
 end offset: 9614933

So we get 15K out of 9M.
By the way, most of the memory here is pretty much
all uniform I guess, because compressing it gets us:
gzip: 1934169
bzip2 -9: 1462551

So even with aggressive compression, we probably won't be able to get
below 1.5M for memory, two orders of magnitude above device state.

Sounds convincing?
