This function should do the trick.
haiku/headers/posix/malloc.h:20
extern void *memalign(size_t alignment, size_t numBytes);

I think something like... 

#elif PLATFORM(HAIKU)
    void *address = memalign(BLOCK_SIZE, BLOCK_SIZE);
    memset(reinterpret_cast<void*>(address), 0, BLOCK_SIZE);
#else
   ...

might just do the trick.

I'm not kernel guru, but hopefully this gets you somewhere.
