Subject: Offtopic? - I have a vmlinuz-3.2.0-rc7+ kernel file that will not
 load -- ("invalid magic number") with the latest Ubuntu grub2 (1.99-14ubuntu2)

Sorry to ask a potentially off-topic question, but I have received no
help from the GRUB2 mailing list.
The reply I got was:
     "Well apparently the number you gave it wasn't magic ;) just a
joke. I really don't have a good answer , I wish I did. Sorry , I just
needed to clown for a bit."

If noone has time to help, no problemo.  I suppose that when Canonical
releases the final 12.04 that the problem will go away with a fresh
install.

I have a 3.2.0-6 kernel that Canonical built which successfully boots.
 I have tried building a Linus GIT tree kernel using the .config that
Canonical used, but it still fails to boot.
My best guess is that perhaps there is either a problem with my Grub2
(1.99-14ubuntu2) installation, or that something is amiss with my
toolchain.

I am running a WUBI install (the root filesystem is located in a
loopback mounted file on my Windows 7 NTFS filesystem).   The
distribution is Ubuntu 11.10 upgraded to 12.04 (Precise Pangolin).
