I just played with this one and tried
	qemu -monitor stdio -cdrom ~/iso/KANOTIX-2006-CeBIT-RC3.iso -m 256 -usb -soundhw es1370 -localtime -kernel-kqemu
that gave me the panic mentioned above again!  Looks like at least
parts of the qemu-piix4-udma.patch from the IDE DMA hack are still
needed (you omitted this patch probably because it no longer applies to
the used cvs snapshot, which is also why I removed the entire DMA hack
from the update I posted, but then I forgot that I still had the
patched bios installed when I first tried -kernel-kqemu...)
