Linux-VServer has some extra quota features, not quite what you're
asking for but perhaps relevant for looking at a patch playing with
quotas on a recent kernel.  The way it works is that you bind mount 
parts of the VFS to another part, and the new mount can have seperate
quota settings.

The most recent split out patch for that is at:
 
http://vserver.13thfloor.at/Experimental/del-2.6.16-rc1-vs2.1.0.9/40_quota.diff

(see it colourised in my gitweb -
http://vserver.utsl.gen.nz/gitweb/?p=vserver.git;a=commitdiff;h=04a1f42903356f18ebdb89613c50923e54506536
)

But it might not stand on its own just yet; it probably at least needs
the Bind Mount Extensions (bme) patch too; it's probably easiest to
apply the entire VServer patch for experimentation.
