Actually, these "other" operating systems avoid the issue by not 
offering the functionality in question at all.  We make the obviously 
shaky assumption that our users are willing to think and apply a little 
common sense to the situation.

You remember incorrectly.  The 64MB problem was licked when I managed 
to steamroller Sean and Jonathan's VM86 work into the system in order 
to use the BIOS.  Likewise, I can in all modesty claim credit for 
fixing the very problem that you're whining about in the 4.x branch as 
well.  

I'm also responsible for the workaround in the 3.x branch.  I'm not 
sure just why it is that the easier it is to work around a problem, the 
more people whine about it.  It's documented, it's massively discussed 
in the list archives, and yet still people find it somehow "too hard".  
*sigh*.
