Wiki update: bootable usb stock emulation

[Florent THIERY]

Hi

I just updated/developed my previous idea of using the transflash as a
bootable device (mass storage mode).

http://wiki.openmoko.org/wiki/Wishlist:Bootable_USB_device_emulation

* What do you think?
* Could somebody owning a device test it?
* If you have pointers to other resources, please add them/tell me;
more generic information could be interesting, especially about the
memtest method (i have no idea how the payload was generated, or if we
can do the same for others)
* i'd be glad to know how one could simply boot on a regular iso using grub

I'm not sure what could prevent it to work, but it would be great to know.

Thanks

Florent
