Rumor has it that if one is willing to open up the case (thereby voiding the warranty), find the serial port connection points, solder a TTL-to-USB cable (making sure the TTL end never goes above 3.3 volts when operating) to those points and then connecting up the PC to the heavily modified Cybook and running PUTTY on the - turned-on-after-making-the-mods-and-connecting-the-cable - Cybook, one can then cause the underlying Linux OS to "run" the update_kernel file.
I wouldn't try this on a working Cybook which still has its warranty.
