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?

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.

Luka
