It looks like something is odd in your install. I haven't got it set up 
on Windows, so I don't know what may have happened, but:

1) It sounds like "import gdal" works. That's a good start.

2) Your error: "AttributeError: 'module' object has no attribute 'gdal'" 
means that python isn't finding that function, so it has nothing to do 
with registering drivers or anything. I'd guess you have an incomplete 
install somehow.

3) try:

 >>> import gdal
 >>> print dir(gdal).

You should get a LOT of stuff, including Open(). If you want to make it 
a bit easier to see what you've got:

 >>> for i in dir(gdal):
...    print i

Let us know what you get, and maybe we can help.
