Well, this is really a matter of bootloader. You can put a kernel
image with embedded ramdisk into flash and get it loaded by Redboot
or U-Boot (there's quite a couple of open source bootloaders, I prefer
these two). This is the simplest option if you have big RAM and
need only small userland.

Other question is using the flash for a filesystem. NetBSD as of now
does not support it (no flash chip driver, no "special flash
filesystem").
