Your msdosfs partition is probably larger than 1 GB. Anyway, the cluster
size of your msdosfs partition is 32 kB (it has to be that large for partitions
larger than 1 GB). Unfortunately, NetBSD currently supports only cluster sizes
up to 16 kB. The limiting factor is the (port-independent, anyone no why this
is in the generic code?) definition of MAXBSIZE as 16384. Changing this
definition in sys/sys/param.h might help, but almost certainly you have to
change some other definitions as well, as the larger buffer size will eat
into the kernel virtual memory space.
