The first problem is that NetBSD passes the command line arg in the parameter that FreeBSD expects the loader metadata to live. There's no real error checking on this, so it results in a crash very early on in the boot. I disabled this test, and it managed to get a bit further in the boot before crashing with an invalid instruction exception. This is most likely a symptom of the NetBSD loader not doing an icache sync somewhere along the line. That mightn't be too hard to locate. later, Peter.
