Maybe Qi is not looking in where we think it was

SD Card EXT2 P1 Kernel
boot/uImage-GTA02.bin
 root=/dev/mmcblk0p1
SD Card EXT2 P2 Kernel
 root=/dev/mmcblk0p2

I get it, Qi expects the kernel to be on the same partition as the
root file system, unlike that created by the Debian install.sh script.
root at om-gta02:~# mount
/dev/mmcblk0p1 on /media/card type ext3 (rw,data=ordered)
/dev/mmcblk0p2 on /media/mmcblk0p2 type ext2 (rw,sync)
so I
# mv /media/mmcblk0p1/uImage-GTA02.bin /media/mmcblk0p2/uImage-GTA02.bin
and edited out /dev/mmcblk0p1 from /media/mmcblk0p2/etc/fstab .

And low an behold,
after a whole minute of starting at a dark purple screen (as if you
were already in production mode with not a single message about what
is taking so long, from pressing power till now,) a X appears, and it's
Debian's nodm!

Conclusions: Debian team: notice that you'll have to ln or cp to
uImage-GTA02.bin and not just uImage.bin to match Qi, and of course it
should all be on the same partition... root and boot.

As for booting into Debian from NOR, hmmm, well if Qi skips vfat
partitions, then we can still have that too.

Several misconceptions on http://wiki.openmoko.org/wiki/Qi , "I'll try
to clear them up".

And Qi team: please turn on the verbosity, starting at the purple
screen can come after you've sold your first gold or platinum record
album of a telephone.

I don't suppose Qi is flexible like grub2 or whatever, so we will just
have to cater to where it puts things.
