Hi Till,

Thanks for the response.  Perhaps you misunderstood me, but I certainly 
wasn't expecting you to support an old standard!  I was envisioning me 
doing the work, either way...Anyway, Joel has suggested I do the same, 
for similar reasons.  Given that I've always felt the new model would be 
better, it seems I've enough good reasons for changing what already 
works.  Only problem is that I don't have any information about the 
differences between old and new.  Do you or anyone else know where I 
should look?  Or at the very least, suggest one or two good example 
PowerPC BSPs that implement the new exception model?

Thanks!
