It doesn't matter that the total memory is not documented, as long as it can tell you the true value.
The concern is that lack of spec documentation makes it harder to maintain the code. Like the GL_ATI_texture_compression_3dc code, which is essentially based on guessing. However, for ATI_meminfo we have your info in the mailing list archives, and if the extension is eventually updated its ok I guess.
I'll send the patches on monday with a few minor improvements.
