I think the blob should only be copied (to me "relocate" involves more
complex operations than just copying) when necessary.

And I guess this restriction is also true for ramdisk images, or am I
wrong?

In any case, I think it wouldbe a good idea if the 16M limit was not
hard wired, but could be overwritten using the "initrd_high" variable
like we can do for ramdisks.

What do you think?

Thanks.

As usual, this being a 1.3.x release, I haven't  even  compiled  this
kernel yet. So if it works, you should be doubly impressed.
