The significant difference you should see between vm.old_contigmalloc
settings is allocation from the bottom of memory (=1) versus the
top (=0).  Is lnc(4) providing incorrect information to busdma about
what region the DMA can work in?  This sounds an awful lot like the
call to bus_dma_tag_create(9) is bogus.
