I don't think that intermediate (void *) cast should matter (I tried
it out of desperation, but it didn't help, just as I expected).

Staring at the kloader_sh3_boot assembler I don't see anything wrong
with it.  Also, as I have found how to control Jornada LEDs I was able
to use them to confirm that the kloader_sh3_boot executes up to the
final jump to the kernel.  The very first instructions of the kernel
also tweak a LED and enter a long delay loop, but that doesn't happen
when I try to reboot.  The machine resets to WinCE reporting TLB miss
exeception (sometimes load, sometimes store).
