In case this board isn't missing for a particular reason, you may want to add it as unsupported. The problem is its usage of NVIDIA MCP65. I reported the output a while ago, but here again the short form:
$ sudo ./flashrom flashrom v0.9.3-r1370 on Linux 2.6.39.3 (x86_64), built with libpci 3.1.7, \ GCC 4.5.1 20101208 [gcc-4_5-branch revision 167585], little endian flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK. Found chipset "NVIDIA MCP65", enabling flash write... \ This chipset is not really supported yet. Guesswork... SPI on this chipset is WIP. Write is unsupported! Mapping NVIDIA MCP6x SPI at 0xfec80000, unaligned size 0x544. Please send the output of "flashrom -V" to flashrom@flashrom.org with your board name: flashrom -V as the subject to help us finish support for your chipset. Thanks. OK. This chipset supports the following protocols: SPI. Found chip "Winbond W25X80" (1024 kB, SPI) at physical address 0xfff00000. No operations were specified.
