Updated Fedora ARM qemu images?

I cannot get qemu-system-arm to boot any of our F17 kernels, but
here's what I did anyway.

# Make a disk image:

$ wget 'http://fedora.roving-it.com/rootfs-f17-hfp-alpha1.tar.bz2'
$ bunzip2 rootfs-f17-hfp-alpha1.tar.bz2
$ virt-make-fs -s 2G -t ext3 -F raw --partition=mbr rootfs-f17-hfp-alpha1.tar disk.img
Formatting 'disk.img', fmt=raw size=2147483648 
$ ll disk.img 
-rw-r--r--. 1 rjones rjones 2147483648 Mar 23 05:47 disk.img
$ virt-filesystems -a disk.img --all --long -h
Name       Type        VFS   Label  MBR  Size  Parent
/dev/sda1  filesystem  ext3  -      -    2.0G  -
/dev/sda1  partition   -     -      83   2.0G  /dev/sda
/dev/sda   device      -     -      -    2.0G  -

# Extract the kernels from the tarball:

$ tar tf rootfs-f17-hfp-alpha1.tar | less
$ tar xf rootfs-f17-hfp-alpha1.tar ./boot/

# Try to boot it one of the kernels in the boot/ directory:

$ qemu-system-arm -m 256 -M versatilepb -kernel boot/vmlinuz-3.3.0-0.rc4.git3.1.fc17.armv7hl -initrd boot/initramfs-3.3.0-0.rc4.git3.1.fc17.armv7hl.img -hda disk.img -serial stdio -vga std
Uncompressing Linux... done, booting the kernel.

It just hangs at this point using 100% CPU with no output.  The other
kernels don't even seem to get that far.
