Asa you probably do not want to kill your standard tree, unpack the Realtek 
version normally, cd to where it unpacked, and do a make. Once it builds, do the 
following:

sudo modprobe -rv rtl8192se
sudo modprobe -v mac80211
sudo insmod rtlwifi.ko
sudo insmod rtl8192se/rtl8192se.ko

Try it first with the default parameters. If that fails, use "ips=0".
