I didn't realize that you changed maxcpus == smpcpus by default so my 
testing wasn't valid.

If I do the following:

x86_64-softmmu/qemu-system-x86_64 -hda ~/images/linux.img -snapshot -L 
~/git/qemu/pc-bios -smp 1,maxcpus=16

I get 'Not responding' errors from an Ubuntu server guest.

You can pull http://repo.or.cz/w/qemu/aliguori-queue.git for-jes

To get my built version of bios.bin.  Please try to reproduce this issue 
with these bits and let me know if you have trouble with it.
