Networking code running in ROM

Any reason why the networking code wouldn't like to run in ROM?

I can boot a farily functional kernel from ROM without networking, but with
networking it fails right after "IP Protocols: ICMP, UDP, TCP". I've traced
it and it seems to fail in various places inside networking, depending on
what else I build into the kernel and how I initialize data (copy
initialzation data to cached or uncached ram).

Oh, there's a twist: I can get it to run with networking in uncached ROM,
just not with networking in cached ROM.

Any ideas? Does it need special alignment? Does it self-modify? Any thing
