Ward - do you have a continuity tester?
I have a multimeter.
Great!
Could you see if the SPI flash chip is connected to the Super IO?
They are about 5 or 6 cm apart.
It's not really possible to tell from visual inspection. Maybe with some measurements.
I took some additional pictures of the area between the superio and the soic chips. There's an unpopulated patch that is marked as 'SPI_EN' near the superio chip - not sure if that is related. Looks like it would fit a jumper or a 2 pin connector of some sort.
Yep, that's a jumper all right. I wonder what it does. Maybe we'll find out.

If I get a high-res photo of the Super IO and the flash chip area I can mark the pins that should be connected on both to get a yes/no indication.
Yes please :) Let me know if the pictures suffice.
Good photos!
I put some labels on interesting pads on the soic detail photo; available at: http://stuge.se/m57sli_soic_detail_labels.jpg
We want to investigate two things:
1. Dual flash chip mod on this board 2. What is driving the flash chip - super io or southbridge?
For 2 I need to put some labels on a super io photo, so let's start with 1. For the first iteration, please check:
* which signals are connected straight across between U5 and U9. (I suspect SI, SCLK, HOLD#, VCC, GND, WP# and maybe also SO are all connected across.)
* what Q4-1, Q5-1, R99-1 and R102-2 connects to on U5, if anything.
