I have found answer. under my 1.5 theme, there is a template/review/helper/summary.phtml which is eventually called by getReviewSummaryHtml function and overridding its base file. with below code
<p class="rating-links">
<a href="#customer-reviews"><?php echo $this->__('%d Review(s)', $this->getReviewsCount()) ?></a>
<span class="separator">|</span>
<a href="#review-form"><?php echo $this->__('Add Your Review') ?></a>
</p>
it assign a direct ID to respective link and jump to review portion on the product view page rather than load a review/product/list page in base design. I did not copy that summary.phtml file into my theme after upgrading.... hope this help those using above method to show review on product view page...
