(and I guess the same applies for NVIDIA and ATI with their 'shared' memory approach).
you are talking about totally different "issues"
integrated graphics actually use part portion of ram, how it uses depends on manufacture and how much you set it in bios (if there is option)
example server 2008 R2 64bit with onboard geforce 8200, takes about 130mb of ram
which is accurate,
if your statement would be true, i would be missing over 1.8gb (that included dedicated memory 128mb that is set in bios + shared memory)
problem with 32bit system is that it can only address 4gb of memory, total memory that includes ram, graphics memory.
again your problem was with 32bit OS
