Apple has released a software update for at least the 15-inch MacBook Pro, and possibly the 17-inch as well (I just have a 15-inch). ExpressCard Update 1.0 "resolves an issue that prevented the system from sleeping when some cards are inserted in the ExpressCard/34 slot." Have at it boys and girls.
Also, do not adjust your display - the funky color scheme you see in my screenshot is the work of ShapeShifter, Unsanity's GUI theming utility.
[UPDATE: At least one commenter has confirmed that this update appears for the 17-inch MacBook Pro as well.]
