Hi Booxtor.
Do you have any information about the firmware discussed in this thread?

Btw.: An official source with - say official signatures, or at least published MD5 checksums, would perhaps be a good idea. Embedded devices (smartphones etc.) _are_ under attack and included in botnets, nowadays.
Otherwise: kernel sources? *nag*
