I have looked at original linux source from Mapower and added some description.
I also don't have schematics...

Is this file (kwbimage.cfg) 100% clone from any existing file already mainlined?
No, but I did not check with all .cfg files. Should I?
- /* Multi-Purpose Pins Functionality configuration */
- u32 kwmpp_config[] = {
MPP0_NF_IO2,MPP1_NF_IO3,MPP2_NF_IO4,MPP3_NF_IO5,MPP4_NF_IO6,MPP5_NF_IO7,
I think these are used for NAND
MPP6_SYSRST_OUTn,
Reset signal
MPP7_GPO,MPP8_TW_SDA,MPP9_TW_SCK,
MPP8-9 I2C
MPP10_UART0_TXD,MPP11_UART0_RXD,
Serial
MPP12_GPO,
This should be MPP12_GPIO as it's a reset button
MPP13_SD_CMD,MPP14_SD_D0,MPP15_SD_D1,MPP16_SD_D2,MPP17_SD_D3,MPP18_NF_IO0,MPP19_NF_IO1,MPP20_GE1_0,MPP21_GE1_1,MPP22_GE1_2,MPP23_GE1_3,MPP24_GE1_4,MPP25_GE1_5,MPP26_GE1_6,MPP27_GE1_7,MPP28_GPIO,MPP29_GPIO,MPP30_GE1_10,MPP31_GE1_11,MPP32_GE1_12,MPP33_GE1_13,MPP34_GE1_14,MPP35_GPIO,
This is OTB button
MPP36_AUDIO_SPDIFI,MPP37_AUDIO_SPDIFO,MPP38_GPIO,MPP39_TDM_SPI_CS0,MPP40_TDM_SPI_SCK,MPP41_GPIO,MPP42_GPIO,MPP43_GPIO,MPP44_GPIO,MPP45_GPIO,MPP46_GPIO,MPP47_GPIO,MPP48_GPIO,MPP49_GPIO,

As per your schematics, please document possible MPPs being used for what purpose.
I dont have schematics, but this values are proven to work. This patch has been in OpenWrt for quite some time, this is updated and cleaner version...
+#define CONFIG_IDENT_STRING " Iomega iConnect Wireless"
The strings looks to be too long, is it possible to shorten it?
Would this be ok:
#define CONFIG_IDENT_STRING " Iomega iConnect"
Reset other thinks looks okay to me.
Great.
