AFAIK none of the rtl8187 devices are non-USB... probably a NACK then, but I should ask Serafeim if there is a reason for him to submit this patch? (other than "it says dma"...) 

There are some devices driven by b43/b43legacy that implement only 24-bit DMA.
For that reason, they need to allocate DMA buffers in the low 16 MB of RAM. For
rtl8187, that consideration does not apply.
