Try this:

<?php
$my_cats = array( 1, 2, 3 );
$my_maxposts = 7;
foreach ( $my_cats as $cat_id ) {
query_posts('cat=' . $cat_id . '&posts_per_page='. $my_maxposts );
while (have_posts()) : the_post();
ob_start();
?><li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li><?php
$my_results[$cat_id][] = ob_get_contents();
ob_end_clean();
endwhile;
wp_reset_query();
}
for ( $i = 0; $i < $my_maxposts; $i ++ ) {
?><ul><?php
foreach ( $my_cats as $cat_id ) {
echo $my_results[ $cat_id ][ $i ];
}
?></ul><?php
}
?>


Tell me if you need any explaination

(soz, small bug, just fixed!)


Andrzej comments:

In case you wanna view also the excerpts after these headlines, you can try this:

<?php
$my_cats = array( 3, 4, 5 ); // define your category IDs here
$my_maxposts = 7; // you can switch the number of last posts here

foreach ( $my_cats as $cat_id ) {
query_posts('cat=' . $cat_id . '&posts_per_page='. $my_maxposts );
while (have_posts()) : the_post();
ob_start();
?>
<li>
<h2><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></h2>
<div class="post" id="post-<?php the_ID(); ?>"><?php the_excerpt(); ?></div>
</li>
<?php
$my_results[$cat_id][] = ob_get_contents();
ob_end_clean();
endwhile;
wp_reset_query();
}
for ( $i = 0; $i < $my_maxposts; $i ++ ) {
?><ul><?php
foreach ( $my_cats as $cat_id ) {
echo $my_results[ $cat_id ][ $i ];
}
?></ul><?php
}
?>
