Since the only difference between echo requests and echo replies is the

Um, no. That will *not* result in correct checksum. Please, RTFRFC 1071.
I verified this works for echo request/reply on my IA64 box,
double-checked with ethereal/wireshark. Is there something specific in
RFC 1071 that I should be looking for?
