This should not make a difference, but be careful to not trash the register.

This bug was caused by the packing of the bcm43xx_dma and bcm43xx_pio
structures into a union.

This is the starting point to make the driver out-of-order-MMIO-stores safe.
There are more mmiowb() needed.

This has a potential to fix the >1G bug. But I can not test that, yet.

It seems to me that the today's wireless-2.6 git contains bcm43xx which
does not free txb's correctly, if I understand it right.
Consider a situation where a txb with two skb's is sent down.
The dma_tx_fragment will save the pointer to meta->txb of the first
fragment. If fragments are freed in order, ieee80211_txb_free frees both
skb's when the first fragment is processed. This may result in reuse
of the second skb's memory.
This danger is rather remote, but it seems to me that the patch
below not only fixes the problem, but also makes the code simpler,
which is good, right?

The proper fix for this is to move IRQ enabling to the end of
init_board. But this is nontrivial and needs to be done with care.
Stay with this cheap workaround for now.
