Hmm, I thought there was an option for this but I can't find it
in the config, so I must have been misremembering somehow.

Not even "Uncompressing the kernel" ?

If you want to track down what's going on then you'll need to
connect an ARM gdb up to qemu and single step through the boot
process, I'm afraid.

I think the mainline kernel sources should in theory work
(in particular if they work with 512MB then that's a good
sign...) but I'm not a kernel expert; mostly I use other peoples'
prebuilt ones.
