flasher-2.0 -k <imagename> -f -R is the linux version of the flasher (command line based)
flasher-2.0 is the command used.

For you to be able to use it you would have to use some kind of linux installation. You should be able to use a livecd.
I recommend you to check out the wiki at www.maemo.org before doing any replacement of the kernel on your device, so you will have a bit more information and comprehension of the subject.
