Something like the following should do.

qemu-system-arm -M z2 -kernel arch/arm/boot/zImage -no-reboot \
    -initrd rootfs-armv5.cpio \
    --append "rdinit=/sbin/init console=ttyS0" \
    -nographic -monitor null -serial stdio

where the kernel is built with pxa_defconfig.
Machine name can be any of the pxa machines (akita, borzoi, spitz,
tosa, terrier, z2, or mainstone). The initrd is from:
