grub is "No setup signature found...," which, imho, comes from
arch/i386/boot/header.S. I tried printing out the value of setup_sig like so

I hitted the same error message with v2.6.23-rc1-171-ge4903fb.
No problem with v2.6.21-3770-g01e73be.
Seems there has been some cleanup of the i386/boot code.
Anyone can give a quick clue, or should I do a bisect?

The bisect will almost guaranteed show a change at the change to the new
setup code. The message means that the setup code wasn't loaded
correctly into memory; the big question is *why*.

What distro/version of grub are you running? I'm wondering if there are
some old version of grub out there which did the "load four sectors"
way-anciently-obsolete crap; the other possibility that comes to mind is
setting up the stack in an invalid manner.
