This module has the options:
-Module pages assign: all pages
-PHP CODE:

$vm = JomGenius("virtuemart");
if ($vm->check( "pagetype != cart") && $vm->check( "pagetype != user") && $vm->check( "pagetype != orders") && $vm->check( "pagetype startswith none of shop.cart, shop.savedcart, checkout" ) ) && $option == 'com_virtuemart'){
return 253;
}
if ($option == 'com_k2'){
return 253;
}
if ($option == 'com_xmap'){
return 253;
}

But i see the module when i confirm the order...

i saw this topic of you http://www.metamodpro.com/forums/topic?id=550 but not works for me...i do:
$vm = JomGenius("virtuemart");
if ($vm->check( "pagetype != cart") && $vm->check( "pagetype != user") && $vm->check( "pagetype != orders") && $vm->check( "pagetype startswith none of shop.cart, shop.savedcart, checkout"&&  $option == 'com_virtuemart'){
return 253;
}
if ($option == 'com_k2'){
return 253;
}
if ($option == 'com_xmap'){
return 253;
}
