They (we) are stuck at the same place as I. The eabi version 

a) kernel error - nwfpe: bad structure size - I will dump the structure 
shortly...
b) with my latest eabi build (thanks, Michael!) 
a statically linked init=/hello_world does run 
but doesn't print any output or write a file. Does successfully 
call "sleep", and does successfully kernel panic afterwards. (it used to 
just hang) I might actually be past the compiler issues and into a setup issue, 
I will try a few more system calls.

I have enough spare brain cells on this now to take this much further this 
evening, and I guess I should probably switch lists.

cool. rh9 is heading for the junkyard as soon as I build something stable 
here for this and ppc.

I am very pleased so far.
