if you have the latest release, you can
set the current page number with the
'currentPage' option:

$options = array(
'mode' => 'Sliding',
'perPage' => 3,
'delta' => 2,
'itemData' => array('a','b','c','d','e',),
'currentPage' => $_COOKIE[$pageId],
);
$pager =& Pager::factory($options);

Thanks, but it still doesn't seem to work because I have a different
page variable, so I would still like to use the 'urlVar' option as well.

Any ideas?

Maybe something like this:

Line 1128:
if (isset($_REQUEST[$this->_urlVar]) && !isset($options['currentPage'])) {
$this->_currentPage = (int)$_REQUEST[$this->_urlVar];
}

Better yet:
if (isset($_REQUEST[$this->_urlVar]) &&
$options['currentPage'] !== null)) {
