  Log:
  Fix burning of CD's that got broken by the GEOM'ification.
  
  GEOM was not designed to handle media that does not have
  a size. Blank CD's are of that type, so cheat and set the
  media size to -1. This allows burning to work, but makes
  GEOM issue outofrange reads that makes the ATAPI subsystem
  spew out a few warnings. GEOM should be tought about this.
  
  GEOM was not designed to handle changing the sectorsize
  between opens. Writing multitack CD's with both audio and
  data tracks needs to change sector size on the fly. We
  cheat here and stuff the current sectorsize into GEOM
  private internals. GEOM should grow some clean way for this.
