[coreboot] SPI in-system programming

I need a way that I can test images without actually being in the same
location as the board I'll be testing them on. What would you guys
recommend for programming an SPI chip with it still on the
motherboard? There is no ISP header, and the flash chip is socketed,
the board will be a Zotac Atom/NM10 ITX board. I've seen programmers
that explain how to isolate the signals so their programmer can be
used to do it, but does it require a special programmer, or is it
something that could be done with a $20 ebay programmer and a little
wire? And can the board be operated with the programmer still
attached? I'm getting a lot of conflicting info, hoping someone can
clarify this.

If this doesn't work out, how can I flip back and forth between a pair
of SPI chips?
