I usually hide my skip to content link through CSS and send the link off the
screen. 

#skipnav{
	position: 			absolute;
	left: 			-1000px;
	width: 			990px;
	font-size:			1px; 
	line-height:		1;
}

Here is an example page of where I used this:

Hopefully this works on a screen reader. Let me know if it doesn't.
