Hello Debian :-)
It took me some time to answer because I wanted to do some more tests
prior to answering.

No I did not find any procedure that could restore the stick to its
full original capacity.
I did some more research and tests (see below) with no success
and I lost hope, sticking with my now 1Gb USB stick.
So I think the installation guide should at least state:
- there are some risks to lose original capacity
- do a full image backup to restore the USB-stick afterward
... and that could make this ticket closed since we haven't
anything better to propose so far. Of course I'm still interested
to read there if someone can provide a solution.
Tests done

1. dd

I have used dd again => still 1.0Gb capacity :-(
$ sudo LC_ALL=C dd if=/dev/zero of=/dev/sdb
dd: writing to `/dev/sdb': No space left on device

SDFormatter
-----------
The "SD Association" was mentionned many times on help forums, etc.
along with their http://www.sdcard.org/consumers/formatter/
It could only run on Windows systems. So I had to get a VM with
Windows on it to be able to test it.
I did all the possible format operations (quick, full, erase on | off,
format size adjustment on | off) with no success.
I suspect the solution to be in the MBR somehow ... and I don't know
what to modify *inside* the MBR.

parted behaves very strangely on my Debian "Lenny" stable. It accepts
only to work on mounted partitions. Is that how it should be?
