Current architecture looks like this:

hardware -> grfXX -> iteXX -> ite -> console

Where XX is hardware-dependent part. Things used only by ite (like putchar or 
cursor) were put into iteXX.

I don't know ;). This grf+ite thing probably originated from hp300 port, but 
hp300 has migrated to wsdisplay some time ago. 

Maybe the person who did this work could help us understand what needs to be 
done ;-).
