I too have that GVP combo card. And it has 1mb soldered directly though. It's either 1mb or 4mb - not 2mb (that I have ever seen).
You've got a jumper problem mate! Those cards have a ton of jumpers on them. If they are not set properly, the RAM will not autoconfig or be recognised at all.
Check out this link to get the proper jumper settings. If you still continue to have problems, LMK and I'll zap over or post a hi-res scan of my card.
LinkyJ12 I think may be your problem...
