core systemlinks help please

Because of page width limitations with my site, I have disabled the sidebar (G2, Matrix). Therefore, I now cannot have the cart sidebar and was wondering if there is any way of adding cart.ViewCart to the core.systemlinks??

Would it be something like editing the theme.tpl to:

<div class="gbSystemLinks">
{g->block type="core.SystemLinks"
order="cart.ViewCart core.SiteAdmin core.YourAccount core.Login core.Logout"
othersAt=4}
</div>

or

<div class="gbSystemLinks">
{g->block type="core.SystemLinks"
order="core.SiteAdmin core.YourAccount core.Login core.Logout"
othersAt=4}
<span class="block-core-SystemLink"> <a href="http://www.mysite.com/main.php?g2_view=cart.ViewCart">View Cart</a> </span>
</div>

am a complete gallery n00b so helpm much appreciated. Many thanks
