Has anyone tried the latest Kamikaze release (7.07) with the Meraki's stage2?

I can't get it to work.  I already fixed the two obvious problems (magic eight byte header, wrong baud rate), and the same kernel works if I decompress it on my host system and load it via tftp.  The stage2 loader prints "starting linux" and a carriage return and then stops.  I even dumped RAM after rebooting the Meraki right after it locks up, and it looks like the decompressor did something sensible.  It's hard to be sure though, since the RAM develops errors very quickly when you don't power it :-)

I have three Meraki boxes to set up and I was hoping to do it without messing with the RedBoot config, just because it will be easier to go back this way.  But unless someone knows what I'm doing wrong, I'll probably drop in a gzipped kernel instead tomorrow.
