Well, show-devs gives (this is from memory, so I might have it wrong):

/vme@1,0efe00000

(It also shows "iscsi" at the same address ... internal SCSI?)

The thing that I'm stuck on is that the vme support for the Sun4 and the
Sun4m are quite different, and I'm not a Sun guru at all :-(  Would
the VME support for a Sun4c look more like the Sun4 or the Sun4m support?
