Having a quick poke through the new Safari binary yields the following strings:
  
  $ strings /Applications/Safari.app/Contents/MacOS/Safari | grep DebugSafari4
  DebugSafari4TabBarIsOnTop
  DebugSafari4IncludeToolbarRedesign
  DebugSafari4IncludeFancyURLCompletionList
  DebugSafari4IncludeGoogleSuggest
  DebugSafari4LoadProgressStyle
  DebugSafari4IncludeFlowViewInBookmarksView
  DebugSafari4TopSitesZoomToPageAnimationDimsSnapshot
  DebugSafari4IncludeTopSites

*NB: Need to restart Safari after changing any of these.*

When both set to NO it restores the blue loading bar behind the URL.

  $ defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
  $ defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO

Switches off the new URL autocomplete menu and goes back to the original one.
