Why doesn OpenGL hardware acceleration work with multiple monitors?

In Windows 98, Microsoft decided to disable OpenGL hardware acceleration when multiple monitors are enabled. In Windows NT 4.0, some drivers support multiple monitors when using identical (or nearly identical) cards. I don’t believe multiple monitors and hardware accelerated OpenGL work with different types of cards. I don’t know the story with Windows 2000, but it’s likely to be similar to Windows NT 4.0.
