the_post_thumbnail() takes an optional second paramter which controls
the <img> tag attributes. Unfortunately the width and height
attributes are applied regardless of this parameter.

Therefore the only way to change the width and height attributes is to
 use the 'post_thumbnail_html' filter and do a preg_replace() on the
attributes.

There is a ticket on Trac for this, I'll update this thread when I find it.
