OK, for future visitors of this thread I will post the instructions that made it work for me
First I followed all the instructions of pinoverclock and they were almost flawless, the only thing he forgot was you also needed to insmod the ieee80211-rtl.ko right before the r8187.ko
If you, just like me, are not very enthusiastic about compiling, I will give you my compiled modules which, even though compiled some for kernel power 47 and some for kernel power 46, should work on all power kernels (maybe even stock, who knows, I will not try myself). I use kernel power 46 modified to inject from the internal thing and it works fine
Sorry for the wierd triple extension, blame the forum 488kb limit
Good luck, you just extract the file and insmod all the modules in the following order:
ieee80211_crypt-rtl.ko
ieee80211_crypt_wep-rtl.ko
ieee80211_crypt_tkip-rtl.ko
ieee80211_crypt_ccmp-rtl.ko
ieee80211-rtl.ko
r8187.ko
Happy Hunting!

EDIT: I forgot remember to rmmod the wl12xx and mac80211 modules before you insmod the next
