It's not perfect, but here's one way:

Have a lead-in page in which Javascript gathers the information you need. Assign the values which Javascript collects into a query string, and submit it to your CGI.

Something like this (untested):

<body onload="location.href = 'script.cgi?height=' + screen.availHeight">

Using "location.href = ..." prevents the lead-in page from appearing if the user pushes the BACK button, it will skip back to the page previous to the lead-in. The weakness with this arrangement is that you'll have an obvious page transfer, but it's the only means to do it.

I was pretty slow typing this, so it's probably already been answered a couple of times in the meantime. Oh well.

Update: Heh, I guess it won't show up if I just type a "<body>" tag in my post, I gotta use &gt; and &lt;. Heh heh.
