Thanks, Robin.  For anyone else who needs to do this,
here's that wrapper:

class ColourSelect(colourselect.ColourSelect):
    "This wrapper for ColourSelect is required to
allow use in XRC."
    def __init__(self):
        self.PostCreate(wx.PreBitmapButton())
        self.SetLabel("")

    def Init(self, Callback=None):
        self.Bind(wx.EVT_BUTTON, self.OnClick)
        self.callback = Callback

Buttons were defined as such:

<object class="wxBitmapButton" name="BUTTON_NAME"
subclass="ColorPref.ColourSelect">
  <bitmap />
</object>

Then, after loading the XRC, I just called Init on
each button.
