I've been looking into this issue a bit more.

When I look at the output of lspci I get:

I see that the VGA card is using slot 01:06.0

In the output of cat /proc/iomem I can see this slot numer 3 times? So I
wonder if one of these if the VGA location if so which one is the real
one i.e. the one I need?
