Is this for DMA or something along these lines? If so, the interface for
allocating "contiguous memory" that was added for the purpose of DDE
should work here as well I'd presume.

(I didn't like how the original interface was designed specifically, and
I don't know whether in has been improved since -- but regardless, it
should get the job done...)

If it doesn't cut it, or this is about something else entirely, could
you elaborate please?
