Yes, that is indeed my problem. I can see why it makes sense not to
support color keying for RGBA surfaces, though it is worth noting that
it works with normal SDL but not with glSDL.

On an entirely separate point, glSDL's SetVideoMode leaks memory if
you call it more than once whilst an application is running. Most of
this memory leak is because calling SetVideoMode a second time
allocates fake_screen without freeing the old fake_screen first,
though there seems to be another leak of about 50kb that I can't work
out.
