The OP wonders if
https://help.ubuntu.com/community/BootFromSD
it will work for Debian. The answer is "probably" but it is questionable
whether the advice to alter the initrd on the SD card need be followed.
Perhaps it was necessary for the Ubuntu kernel at the time the article
was written. The hardware involved would have to be known to more
definitive.
Debian would need to be installed to the SD card and the *same" Debian
installed to the USB stick. lsinitramfs will help confirm whether needed
modules are in an initrd.
