What tools are you using?  My last build log looks OK for the gen405.  I 
been switching tools a lot lately so don't remember whether that is with the
gcc 4.0.1 RPMs, 4.1 branch, or gcc head. 

I do not know if it runs as I have no way to test it.  It is likely to 
require some
modifications for any particular 405 board if it is anything like other

I think all of the PowerPC BSPs except the 40x ones have been converted or
removed at this point.   So this is work left to do.

The other 4xx BSP is the helas403 from Thomas Doerfler and I recall that
he was having trouble debugging it because his emulator is broken.  But a
known good conversion of the gen405 to new exceptions would be welcomed
as would a mechanical (it compiles now) conversion of the helas403.  At that
point, I think old exceptions would be dead.
