I'm afraid not
Laptops are impossibly hard to update hardware for.
Since the chips are built into the motherboards on most units, changing stuff like the graphics card becomes an impossibilty
Some laptop manufacturers do offer a card slot that allows you to upgrade the graphics, but I'm afraid one like yours won't.
It isn't just the memory that matters though, since this will only really help with texture cache, and other bits of information like that, which also sticks by resolution size.
64mb was great back in the day, when resolutions were pretty low in games, and texture sizes weren't pushed so far.
Nowadays though, 128mb will only get you so far even, and 256mb's of video RAM has become the norm.
This is just because of increased resolutions, and texture sizes, and other complex geometry patterns the video cards are now faced with.
This really only leaves me to say that, with that laptop you have, though great for older games, can't and will not be up to the challenge of top of the range games today (Crysis especially), as setting to a lower resolution and texture res can only get you so far.
This type of thing does give you some hope though:
