It is important to distinguish between RAM (real memory) and Address Space. Regardless how much real memory you have as RAM or in the Graphics card - they all need address space. And a 32bit system can only provide 4GBs of that. So whatever memory you add with a graphics card will reduce the address space for RAM. Plus there are a few other smaller "users" that need address space - see here.
The situation is similar - but not the same - with an on-board graphics facility. It has no own memory and uses (shares) real RAM and, of course, address space.
