Hm, this is exactly what I've done, except I used the images/diskboot.img 
w/memdisk (from syslinux) instead of the the kernel and initrd directly.
I compared the MD5 sums of the kernel and initrd from both isolinux/ on the
DVD and from the diskboot.img image and they're exactly the same.  (I did
try booting a kernel and initrd directly from grub, but I used the ones
from images/pxeboot, which I have used in the past (for doing network upgrades
on machines without a working netboot ROM).)  I could try using the kernel
and initrd from isolinux directly with grub, although I doubt that would
make a difference.

Can you tell me what your "legacy USB" settings are in your BIOS?
Is the grub you boot with on your normal internal (PATA/SATA/SCSI) drive?

Is there any way I can more directly debug this?  I don't have a shell since
that comes from stage2, which isn't loaded yet.  I suspect the other remote
debugging options are not yet available either.  Hm, yeah, looking over the
initrd contents, there really isn't much available at all.
