It looks strange indeed - as if the validator saw a page that has 
something like

/* $Id: node.css,v 1.2 2006/09/05 03:50:56 unconed Exp $ */

at the start, as in your CSS files.

The response headers from contain the header
Vary: Accept-Encoding,User-Agent
which _suggests_ that the server _may_ send different responses to 
different user agents. This is a bit far-fetched, though. (I tested with a 
response containing an empty User-Agent value, and the response content is 
normal, i.e. the same as normal browsers get.)

I wonder whether the prologue is useful in practice. It throws IE 6 into 
Quirks Mode, and it isn't really needed, at least in this case since
UTF-8 is explicitly specified in the Content-Type header.
