Photoshop does, but like many things PS, you have to know how. Open  
the info window (in the default setup of CS and CS2, tabbed with  
Navigator and Histogram, always avail in the window menu), and one of  
the fields is XY. If you aren't seeing pixel values, go to the  
preferences->Units and Rulers tab to set it to pixels (default is  
generally inches).

If not to scale it simply will not work, fixing it would usually be  
harder than starting from scratch.
