It's just the kernel too big and I've been trying to move things out to modules or remove completely. I honestly tried to keep things to a minimum.

Busybox is enabled for initrams. For the kernel I don't think it makes any difference if I'm using busybox or util-linux to invoke gcc (arm-linux-gnueabi actually from emdebian.org), maybe that's the problem?

Sure, initrd is here: http://pastebin.com/sdQhJxsn Also, .config is here: http://pastebin.com/mvnkW2DD > .... but, just for a laugh please do tell me the size of the kernel > you've got. i remember doing 2.4.24 kernels and they were only 600k. > we converted to 2.6.8 or thereabouts and that *immediately* shot up to > 900k (exactly the same config options). hilarious. not. I went down from whopping 5MB to 2.1MB I also tried to use a .config file from linux-image-3.2.0-3-iop32x_3.2.23-1_armel.deb but during make it asked for a bunch of new stuff to which I said 'N' and it's still is a big image.
