I bought the MiniEMBWifi a while ago, but I never got it running smoothly with the supplied Fon firmware. I compiled the Fon-ng version myself but I must admit I don't really like the fon-stuff interfering with stock-openwrt behaviour. Besides, running some old-hat kernel didn't improve things either because a lot of packages are broken on this branch.
So I waited patiently until the Ralink chipset was officially added to the SVN. After
patching the code allowing the Omnima board to be selected in the toolchain, everything compiled like a breeze and voilà ... Attitude Adjustment running since a couple of weeks on my lan.
It's running extremely stable at the moment. Only downside is the slow USB interface, limiting bandwidth of samba, FTP or ushare to < 9 MB/s and usually around 4MB/s, which is ok for occasional sharing, but not for multimedia.
