I did a quick linux kernel hack to support the versatile_pci
compatible PCI controller for realview-eb boards.
Using the new stable-0.12 branch of qemu and the new 'realview-eb'
machine type, scp'ing large files into qemu no longer hangs the
network on ARMv6 CPUs.

kernel patch (trivial but ugly):
http://gitorious.org/scottt/linux-arm/commits/realview-eb-qemu
realview-eb-qemu branch

kernel config:
http://scottt.tw/bug/qemu-network-hang/realview-eb-qemu_defconfig

prebuilt kernel zImage:
http://scottt.tw/bug/qemu-network-hang/zImage-2.6.32-realview-eb-qemu-v6

script to launch qemu:

I used the same rootfs.ext2 image that you uploaded.
Sorry for the late reply, other priorities intruded.
