I've been using OPENGL | DOUBLEBUF as flags to set_mode, but on my last 
browse of the SDL source, I seem to recall DOUBLEBUF as having no 
effect, since SDL assumes OpenGL would be double buffered anyway.  
Also, the HW* commands are only relevant for non-OpenGL usage.

Here's what the Vision Egg does (slightly modified):

import OpenGL.GL as gl
gl_vendor = gl.glGetString(gl.GL_VENDOR)
gl_renderer = gl.glGetString(gl.GL_RENDERER)
if gl_renderer == "GDI Generic" and gl_vendor == "Microsoft 
Corporation":
	print "Software rendering -- expect slow frame rates"
