Just realized I forgot to include the requested command outputs. Dough!

Doesn't detect the chip, though whether it's the recent addition of this board as a programmer or the unsupported chip I couldn't say.
If there is a similar 4Mbit chip option you'd like me to try let me know. I think it's perhaps similar to the Am29F040B and MX29F040 ships. I've just forced it as those chips, and hexdump shows the resulting image showing as all one's. I'm assuming it's a bad read, but as I don't know what was on it to begin with, I can't be sure. For all I know, the chip is fried.
Grazie, Daniel Fussell

flashrom is missing support for this chip.
the datasheet can be found for example here: http://pdf1.alldatasheet.com/datasheet-pdf/view/179362/SPANSION/MBM29F040C-7... flashrom reads out the correct ids for vendor (0x04) and chip (0xa4) with the function probe_jedec_common as seen in your log. there is already a define for the chip in flashchips.h: FUJITSU_MBM29F040C
after adding the needed data to flashchips.c it will probably work. you can try copying a similar chip and change it where necessary. patches are welcome of course ;)
For all I know, the chip is fried.
why do you think that?
