You should see nfs traffic.

This used to work, even with the busted firmware in my beige G3.
On the other hand, I got similar problems netbooting my iBook G4 and  
got around it by having OF load the kernel directly, without  
ofwboot.xcf. I'm not sure if your OF version understands ELF binaries  
though, and even if it does it will barf on binaries bigger than ~4MB  
so INSTALL or GENERIC won't work.
Unfortunately I'm not at all familiar with the boot loader. Any chance  
to try an older loader from - for example - 4.0, just to see if it  
even tries to load a kernel?
It can't be too busted though, netbooting via ofwboot works fine on  
sparc64 and the nfs code should be shared.

have fun
Michael
