1. Open /skin1/modules/Manufacturers/customer_manufacturers_list.php

2. Replace:

  <ul class="manufacturers-list list-item">
    {foreach from=$manufacturers item=v}
      <li><a href="manufacturers.php?manufacturerid={$v.manufacturerid}">{$v.manufacturer|escape}</a></li>
    {/foreach}
  </ul>

with:

    <ul class="manufacturers-list list-item">
    {assign var="col" value="0"}
    {foreach from=$manufacturers item=v}
        {if $col == 4}{* Adjust the number of columns *}
            </ul><ul class="manufacturers-list list-item">{assign var="col" value="0"}
        {/if}
        <li><a href="manufacturers.php?manufacturerid={$v.manufacturerid}">{$v.manufacturer|escape}</a></li>
        {assign var="col" value="`$col+1`"}
    {/foreach}
    </ul>

3. Add/replace this code in main.css:

 /* manufacturers list */
ul.manufacturers-list { padding: 0; margin: 0 0 8px 0; list-style: none; clear: both; }
ul.manufacturers-list li { margin: 0; padding: 2px; white-space: nowrap; display: inline; float: left; width:100px; }

Optional postinstallation steps:
- adjust the number of columns: {if $col == 4}
