--- Comment #3 from Roland Scheidegger <sroland at vmware.com> ---
Isn't this mapped as WC?
In this case I'd expect the direction to make little difference, since write
combine of any decent cpu should be able to combine the writes regardless the
order?
Although if it's UC I suppose someone needs to ensure that the maximum possible
size is picked...
