I've been bitten by this in the past, too -- back on the (not too
distant) 2.4.x days. On my case, enabling RAM disk support for my
custom kernel allowed LABELs to be properly understood (I've been doing
it this way since then). My bet is that it would help you too. WARNING:
you might need to compile it as a built-in feature, and not as a module
