So you would have to rip it down to 64MB from 134.. quite hard. And even if it was possible we would have to resign the full update package before trying to apply it, which, afaik, is something we cannot yet do. I'd love to be proved wrong though.
Apparently, after running some tests, the only thing the tv complains about when trying to flash a full valdeuc firmware image is that it doesn't fit. So i think that a "transplant" of a flash from a donor running t-valdeuc should work.
So if you have the skills to solder it, the equipment to flash it and someone willing to send you a full flash dump of a 1gb image (if you're buying it empty), and the courage to do it, well it has some chance of actually working.
Our best bet would be redirecting some of the firmware parts (internet@tv executables and widgets for instance) to an usb key. But again we would need the ability to flash custom images or at least root access to the tv.
if what you say are true, if we chroot entire system, we are able to do a dd if=/dev/flash0 of=/mnt/usb/dump and then write the resulting 1GB image (first 128MB) to the tv with smaller flashrom.
It is true? via a exlink cable we are able to do a full memory dump? (may take hours at 115200bps......)

There isn't dd in busybox you need to install a full busybox first to make dump of a t-valdeuc fw.
