All I can say for sure is later run N64s use newer RAM modules that don't "keep" their memory for 10 seconds when the power to the system is cut. While bilinear filtering is a hardware driven feature, the N64 games themselves determined how intense the filtering was. That link you provided indicates that along with Gameshark codes for each game to disable the filtering completely are codes that just lower the level of filtering.
For all I've said about Mario 64 DS, don't misunderstand. The graphics in the DS version, other than the antialiasing issues, have been improved. Mario, for example, has more polygons and more detailed textures. The biggest upgrade, however, is all the additional stars and areas, and playable characters. It's a worthy enhancement over the N64 original.
The biggest downside isn't the lack of antialiasing, though that is lamentable, it's the lack of an analog stick. Controlling Mario and friends with a d-pad just doesn't work as well in the game, and using the "soft controls" with the touch screen is also very awkward, though sometimes necessary to navigate certain sections. For my part, I'd love to see the DS version properly ported to 3DS, sporting both features added back in.
If you want some details on what I've heard about the application of bilinear filtering on later revisions, check this thread:

It's entirely possible that Nintendo just remapped the instructions for filtering so game requests for one level returned a lower level.

"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
