syslinux and the boot-big.fs floppy image is how I have been doing  
it. Lets you multiboot several different images and keep a usable FAT  
file system for copying files around.

quick and dirty mostly windows instructions:
http://user.dtcc.edu/~ctribo/usb_multi.html

rename boot-big.fs netbsd.img (extension is important)

and create a syslinux.cfg file with:
kernel memdisk
append initrd netbsd.img
