again, working off this openwrt page:
http://wiki.openwrt.org/doc/howto/qemu
on my 64-bit fedora rawhide system and BB-rc3 downloaded images, i
tried to boot just the kernel:
$ qemu-system-arm -M realview-eb-mpcore -kernel openwrt-realview-vmlinux.elf
-net nic -net user -nographic
pulseaudio: set_sink_input_volume() failed
pulseaudio: Reason: Invalid argument
pulseaudio: set_sink_input_mute() failed
pulseaudio: Reason: Invalid argument
Uncompressing Linux... done, booting the kernel.
[ 0.000000] Booting Linux on physical CPU 0x0

CEST 2014
... snip ...
[ 0.721801] VFS: Cannot open root device "(null)" or unknown-block(0,0):
error -6
[ 0.723325] Please append a correct "root=" boot option; here are the
available partitions:

so, unlike what the wiki page says, this kernel does in fact seem to
boot. that's a good sign.
now, try the initramfs version:
$ qemu-system-arm -M realview-eb-mpcore -kernel
openwrt-realview-vmlinux-initramfs.elf -net nic -net user -nographic
pulseaudio: set_sink_input_volume() failed

BARRIER BREAKER (14.07-rc3, r42056)
... snip ...
root@OpenWrt:/#
so that seem to work fine as well.
