I will try to answer the questions raised in hopes you may find the info 
useful.
I can still reproduce the issue with the USB drive.

1. OpenFirmware is Q3C07

I was under the impression that it had eventually failed at some point 
but now it's been stuck for 30 minutes and still I get no output after 
issuing fs-update command.

After 30 mins I aborted to try next steps.

Tried this, issue is still present.

As previously reported, tried with a different USB key and it worked.

Here is output of fsck.vfat:
[icarito at travelmate ~]$ sudo fsck.vfat -nV /dev/sdb1
fsck.fat 3.0.24 (2013-11-23)
0x41: Dirty bit is set. Fs was not properly unmounted and some data may 
be corrupt.
Automatically removing dirty bit.
There are differences between boot sector and its backup.
This is mostly harmless. Differences: (offset:original/backup)
