Yes, I have a vmlinux built into my BBL. I didn't actually look closely at the command line I was copying and see that vmlinux in there, my guess would be that it's getting ignored. I don't remember if upstream BBL actually works with the split bbl/vmlinux setup, I've kind of stopped paying attention to BBL as I'm just waiting for someone to tell me instructions as to how to use a real bootloader... :)
I'm building master from QEMU as of a few weeks ago

in general once we get a port upstream I jump over to using master from upstream as that way we'll find any bugs quickly. Michael Clark has a pretty big QEMU patch queue, but nothing appears to be critical for Linux boot.

Thanks! I'm super excited to get CI stuff up and running as now that we can boot I'm worried people will notice when I screw something up :)
