To use the old-style contextual menus when you click-and-hold on an application's icon in the Dock (i.e. how it worked in 10.5 and earlier), type the following two commands in Terminal (don't type the $):
defaults write com.apple.dock show-expose-menus -bool no; killall Dock
All credit for this hint goes to Jeff Johnson of Lap Cat Software, who blogged about the solution. This hint is a significant update to this one, which pointed out you can use Control-click to get the old-style contextual menus.
[robg adds: To undo this behavior, you can either change no to yes in the above command, or delete the key entirely with defaults delete com.apple.dock show-expose-menus; killall Dock.]
