The apex:inputField component is not supporting the attribute as "disabled".

You can do this via jQuery.  Import the jQuery library as a static resource first -- in my example I named the resource JQuery_1_7_2.  Then you can do this within your page:

 

<apex:page standardController="Account" extensions="TestController">
 	<apex:includeScript value="{!$Resource.JQuery_1_7_2}"/>
	<script type="text/javascript">
		var j$ = jQuery.noConflict();
                var shouldDisable = '{!shouldDisable}';
		j$(document).ready(function() {
                        if (shouldDisable) {
			   j$('input[name$="acctName"]').attr('disabled','disabled');
                        }
		});
	</script>  

.....

<apex:inputField id="acctName" value="{!account.Name}" />

...

You define the property shouldDisable on your controller and can initialize it in your constructor or later in the code:

 

...
    public TestController(ApexPages.StandardController ctlr)  
    {  
       sc = ctlr;
       shouldDisable = true;             
    }
...

      public Boolean shouldDisable 
    { get; set; }

...
