With respect to 16k alignment .. it may be acceptable for this to fail
at boot-time (IMHO, barely) but it usually isn't if a machine has been
'up' for a while.

Does the UMA sub-system reliably work with 4k aligned requests? As an
interim hack, I'd be happy to lose 12kB if it meant a 100% success rate
 on my 2GB laptop. There are much worse things ..

The only questions are, not having looked through the code recently (or
the UMA code at all), how many buffer pools are allocated and is it
possible to allocate a chunk of memory contiguously (for all pools) and
assign dma tags once that chunk is 'trimmed' to an acceptable alignment?
