I think allocating physically contiguous large memory is a bad design and I doubt reserving 16MB physical memory at boot time is acceptable for all machines with USB. Anyway, currently our udl(4) doesn't require such allocation, but has more other problems: http://cvsweb.NetBSD.org/bsdweb.cgi/src/sys/dev/usb/udl.c#rev1.1 --- Izumi Tsutsui
