Ok, here's an updated set including Eric's feedback.  He also made me think a 
little more about the xf86DisableUnusedFunctions change.  I think removing it 
from the core would mean more driver changes than I'd like, so I'll leave it 
up to Aaron to change the way that's done.  We could have a global flag in 
the xf86_config structure to control whether it's called, or maybe change it 
into an xf86_config function pointer like ->resize...

Anyway, this patchset seems to work ok for me.  Any more comments?

Thanks,
Jesse
