I'd bet that mod still works so long as you put the code around:

{vb:raw post.signature}

Instead of:

$post[signature]

So basically replace the code:

{vb:raw post.signature}

With:

<hr size="1" style="color:#678B06" />
			<div valign="bottom" style="width:100%; height:400px; overflow: auto">
			{vb:raw post.signature}	
			</div>

That should work, but I haven't tested it.
