The problem is that kmalloc on Linux always returns contiguous memory
(because Linux maps some range of physical memory 1:1 into kernel
virtual address space). So for a correct implementation we need to
always return contiguous memory (although this will be quite expensive
on Haiku).
Depending on how the alloc/free behaviour is in the code to be ported, a simple
provisional allocator could be added (temporarily), i.e. create a larger area
of contiguous memory and hand out pieces of it.
