Ignore the 'must allocate below 1MB' flag for the TPL_BAR_REG. It is
set on realtek cards, but they work without it (and don't work with
it). The standard seems to imply that this is just a hint anyway, so
this should be harmless. It doesn't appear to be set on any other
cardbus cards that I have (or have seen).
This should make the rl based CardBus cards work again. I've been
running it for about a month now.
