Oops, yeah, thanks.  All I needed to do was

# special skin markup
SDVA($PageTextVarPatterns, array(
  'var:' => '/^:*(\\w[-\\w]*):[ \\t]?(.*)$/m',
  '(:var:...:)' => '/\\(:(\\w[-\\w]*):\\s?(.*?):\\)/s'));
$Blah = PageTextVar("$pagename","Blah");
if ($Blah == "1") $Skin = 'pmwiki';
else $Skin = 'whatever';

I think I had tried to use $pagename without the double quotes
initially, and started throwing in other terms hoping it would work.
It didn't occur to me until just now that I would need it to be in
quotes.
