I think I posted a link to that same bug report. The problem is that
if the BIOS wasn't allocating it before, it isn't allocating it now,
because it's still the same A11 bios that Dell shipped it with. And now
I'm not sure which is more confusing - that it was OK in -0703 and borked
in -0709, or that between two successive boots of the same -0709 kernel
it cleared itself up....
