Sigh, the vsbus files are also mid-uvm/vm changeover. This is rapidly 
becoming too much change in my environment to track. Does anyone have a 
preference for new driver targets ? 1.6 or 1.5? Is the use of UVM going 
into the 1.5 release or is it staying in mainline? Should I use the vsbus 
stuff for the DSSI driver or ibus? Leave me current buffer mapping for the 
SII chip as a private kernel memory or try to use the bus space macros so 
that DMA to them is easier? (currently they are effectively bounce 
buffers). Is there a kern-vax mailing list for asking these questions?
