All RAM pinouts (except the newest, weirdest ones) are JEDEC
standards.  What are the part numbers on the VRAMs that are already on
the board?  Who manufactured them?  As far as I know you should only
be in trouble if they're parts that are old and have been

Of course, getting the board to USE the extra memory after you've
installed it may be a problem.
