I like A for the explicitness, but B is a bit easier to read on an 80 column display.  There's no 'verbose' flag for pciconf, and the '-v' flag has already been claimed for another use; if a verbose flag were to appear, I'd suggest hiding the rev and hdr fields under it and otherwise shortening the line.  However, it's not my bikeshed to paint, and I'll be thrilled with either option A or B or anything in between.

Indeed.  Thanks a lot for working on this.
