Block not showing after layout update

Question

Considering this layout update XML:

<?xml version="1.0"?>
<layout version="0.0.1">
    <checkout_cart_index>
        <reference name="methods">
            <block type="mhquote/request_link" name="mhquote.request.link" as="mhquoteRequestLink" before="-" template="mhquote/request/link.phtml" />
            <remove name="checkout.cart.methods.onepage" />
            <remove name="checkout.cart.methods.multishipping" />
        </reference>
    </checkout_cart_index>
</layout>

When the update is applied the cart page goes from this:

To this:

I can't understand why the new block is not shown, given that:

• a module exists which has mhquote as a unique handler
• the module is correctly set as for controllers in it work fine
• methods block is a core/text_list block, so it should automatically render all child blocks
• the template exists at app/design/frontend/<current_theme>/default/template/mhquote/request/link.phtml
• the Disc_Quote_Block_Request_Link block class exists and extends from Mage_Core_Block_Template, Disc_Quote being the class group handled by mhquote
• the layout update file is loaded correctly as it successfully removes the two checkout links

The block template is really simple, just a <div> with a string I'd like to show:

<div class="hellotest">
     <h1>Hello</h1>
</div>

I can't see where I'm wrong. I keep checking and rewriting it from scratch paying more attention to the namings but I can't seem to show that block.

Any idea why? Thanks in advance for your help.

=== EDIT 1 ===

This is the config.xml for the module:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Disc_Quote>
            <version>0.0.1</version>
        </Disc_Quote>
    </modules>

    <global>
        <blocks>
            <mhquote>
                <class>Disc_Quote_Block</class>
            </mhquote>
        </blocks>
        <helpers>
            <mhquote>
                <class>Disc_Quote_Helper</class>
            </mhquote>
        </helpers>
        <models>
            <mhquote>
                <class>Disc_Quote_Model</class>
            </mhquote>
        </models>
    </global>

    <frontend>
        <routers>
            <mhquote>
                <use>standard</use>
                <args>    
                    <module>Disc_Quote</module>
                    <frontName>mhquote</frontName>
                </args>
            </mhquote>
        </routers>

        <layout>
            <updates>
                <mhquote>
                    <file>mhquote.xml</file>
                </mhquote>
            </updates>
        </layout>
    </frontend>

</config>
