IE6, IE7: stretch the last value of li to the cumulative width of the previous li

Question

Given this markup:

<ul class="grafiek">
    <li class="first-child">item</li>
    <li>item</li>
    <li>item</li>
    <li>item</li>
    <li>item</li>
    <li class="last-child">item</li>
</ul>

How can I do this, cross browser, for example:

In other words: the last element (with a fake pseudo-class last-child) should always be stretched to accommodate the total aggregate width of previous arbitrary sums (within reason), <li>'s

This is what I have so far:

ul.grafiek {
    float: left;
}
ul.grafiek li {
    float: left;
    display: block;
    margin-left: 6px;
    width: 56px;
    height: 66px;
    padding: 12px 0;
    color: #fff;
    text-align: center;
    font-size: 11px;
    line-height: 1;
    background-color: #c5015a;
}
ul.grafiek li.first-child {
    margin-left: 0;
}
ul.grafiek li.last-child {
    clear: both;
    margin: 10px 0 0 0;
    width: 100%;
    height: 23px;
    padding: 0;
    line-height: 23px;
    background-color: #0a2d7f;
}

IE6 stretches the latter <li>to the total width of the parent <ul>. IE7 does not stretch it at all. How can I get these two browsers to work?

PS: Firefox, Chrome, and Opera are waiting.
