I figured it out...

You can't use wx.Bitmap() to create a bitmap from XPM data. You
use wx.BitmapFromXPMData() which allows you to "Construct a
Bitmap from a list of strings formatted as XPM data." 

It still took a bit of trian-and-error to figure out what
"formatted as XPM data" meant: You can't just pass it a list of
the strings from an .xpm file -- you've got to strip out the
"C" stuff.  Maybe that's obvious to everybody else, but it took
me a few guesses...
