OpenEmbedded is buildsystem used to build OpenZaurus, Familiar and few other Linux distibutions (not only for PDA). So when something is added into it then all distros can use it. We have drivers for other CF 802.11g cards and getting this one to build is possible.
But getting it build is one thing, get it tested is other thing.
I just tried to build it and discovered that it firstly need to port to ARM as now it's i386/x64_64 only So sorry - nothing to test.
