multiple loops in category.php

I’m trying to set two columns with five posts in each column, left is one loop, right is the second loop. but I don’t want to specify a category. I want it to open as the selected category, as if i were using a single loop on the page category.php.

in the left column i want the first five posts from category X, and in the right column the next five posts in cat X.

I have checked all the Template Tags and the suggestions for Query Posts. i have hundreds of categories and I don’t want to make a custom category-XX.php page for each category.

any ideas?

thank you
