I strongly agree with the kwargs approach, it makes things clear as to 
what is being set.

I applied this patch and it worked fine.  On my Mac I use the PS 
backend and convert to PDF.  With the default frame width (0.5), the 
frame was not visible using Adobe Reader 6.0. The file printed fine, 
but the on screen viewing omitted the frame. This might be a personal 
problem on my setup, but it might be useful if other people have this 
difficulty. Making the frame width equal to 1 fixes things.

using matplotlib and lovin'  it.
