It is because the first partition is also /media/card in Qtopia and a series of
applications share it with the booting for Debian. The phone number database goes there,
or the OpenStreetMap data, or ...

With vfat there is no symlinks, so one would rename to uImage.bin whataver shall be used.
I would now for instance copy the 2.6.24 version next to the installed 2.6.28 one and
start comparing the two more.

They are intentionally lowercase since they are of internal use only.

I did not know how to change a patch afterwards. I wished you would decide over that
functionality by looking at the latest version. I had added some logics to allow the swap
partition to be the last partition of the device.

Er, yes.

If something went wrong, then cat `ls -lt /tmp/argsToFdisk*|head -1` will print the
commands sent to fdisk.

The -fbpanel bits - right.
