no idea there...

d) the message doesn't really tell you if it's currently enabled or not.
The code just checks if your drm is new enough (in case you've enabled 
dri) and the virtual resolution doesn't exceed the chip limit for 
tiling. But it still will get enabled or disabled based on your current 
resolution, so if you'd switch from an interlaced resolution to a 
non-interlaced one or vice versa it would get enabled/disabled on the 
fly, without any message.

Definitely yes for interlaced, and composite sync should work too.
