The cards will not work in 16K mode no matter what memory address you use
(there is a PR outstanding on this that I'd like someone with the power to
commit to look at before 1.5 -- I don't have the number off-handedly, but if
anyone is interested in furthering the cause, please send me email about it)
but with the fixes there applied I've used the cards at all sorts of memory
addresses succesfully.

Note that in 16K mode those cards map memory in a very strange way (read:
unknown to me, obviously not to the linux driver authors either, as their
driver uses PIO all the time), which means the driver has to resort to PIO
mode to transfer packets in/out of the shared memory.
