In fact the module I used earier was included in rpm kmod-staging from the 
fusion repositary and thus strictly speaking not a part of Fedora. For some 
reason the r8192e-pci module was dropped from kmod-staging and I believed that 
the modules in Fedora would function. Now I know better!

I managed to compile and install r8192e-pci into 
/lib/modules/3.3.1-3.fc16.x86_64/kernel/drivers/staging/rtl8192e/rtl8192e/ 
(I'm running 3.3.1-3.fc16.x86_64 now) and also rtllib.ko, 
rtllib_crypt_ccmp.ko, rtllib_crypt_tkip.ko and rtllib_crypt_wep.ko into 
/lib/modules/3.3.1-3.fc16.x86_64/kernel/drivers/staging/rtl8192e/
However trying to insmod any of them only results in 
insmod: error inserting 'xxx': -1 Unknown symbol in module

They probably depend on each other so I have tested with everyone first, but to 
no avail. They must depend on some other module. I also tested with modprobe, 
but that didn't function either as they are not listed in modules.dep.

Any pointer to how to make a correct entry in modules.dep or what they are 
depending on would be much appreciated.

Best regards
