Add noise texture effect to navbar in CSS

Question

Is it possible to add a noise layer to a navbar in CSS? Like this one:

Either with CSS or background-image (without editing in Photoshop or similar.)

.navbar-inner {
  min-height: 40px;
  padding-right: 20px;
  padding-left: 20px;
  background-color: #fafafa;
  background-image: -moz-linear-gradient(top, #ffffff, #f2f2f2);
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#ffffff), to(#f2f2f2));
  background-image: -webkit-linear-gradient(top, #ffffff, #f2f2f2);
  background-image: -o-linear-gradient(top, #ffffff, #f2f2f2);
  background-image: linear-gradient(to bottom, #ffffff, #f2f2f2);
  background-repeat: repeat-x;
  border: 1px solid #d4d4d4;
  -webkit-border-radius: 4px;
     -moz-border-radius: 4px;
          border-radius: 4px;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffffffff', endColorstr='#fff2f2f2', GradientType=0);
  *zoom: 1;
  -webkit-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065);
     -moz-box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065);
          box-shadow: 0 1px 4px rgba(0, 0, 0, 0.065);
}

CSS currently doesnt support a way to do this reliably (although I think there should be...). I just wanted to specify, you want a small image, and then just to repeat it.

Here is a site with many samples

And here is a custom generator
