   What interrupts is it generating?  int21h is DOS (probably for stdio), int10h   
   is video BIOS (probably to move/hide the cursor).

   Not directly.  conio.h looks to use DOS/BIOS calls, so it's line   
   stream-oriented rather than a screen buffer.   
      
   The main reasons for using $B800 were speed and the fact that writing anything   
   to the lower-right cell using DOS automatically scrolled the screen up, so if   
   it's not doing anything else some simple wrapper functions to set the cursor   
   position and avoid the lower-right cell would suffice.   
      
   Win32 (and OS/2, AFAIK) has a buffer-oriented console, so code using $B800 is   
   directly portable, but since *nix terminals are stream-oriented there's no   
   equivalent.
