Fellow RTL8191SE sufferer here (in a ThinkPad T410.)
In my case, lspci says:
03:00.0 Network controller: Realtek Semiconductor Co., Ltd.
RTL8191SEvB Wireless LAN Controller (rev 10)
The ndiswrapper approach never worked for me.
I compiled kernel 2.6.36 with the driver source I downloaded
(Actually, the driver sources are also in the staging
directory of the Debian 2.6.36 kernel sources. Maybe I did
something stupid, but being in "staging" seemed to interfere
with the driver loading in the compiled kernel. Is it enough
just to move it elsewhere in the tree?)
You also need to install the firmware. I have these files:
Now you're ready for:
In my case, I can see the driver has loaded successfully
because the wireless indicator LED on the laptop turns on.
Then I can start wpa_supplicant and wpa_gui.
ifconfig wlan0 up
wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf &
At the moment, there is just this one line in
Click on SCAN, then when a smaller window pops up, click
on *its* SCAN button. A list of APs will show up. You can
choose an entry from the list by double-clicking. This gives
you a menu to enter a password and/or other parameters.
dhclient -x wlan0
I find '-x' helpful, as without it multiple dhclient
commands may cause problems with multiple dhclient
processes hanging around.
It took me an embarrassing amount of trial and error to get
this far. Hope it will go easier for you!

I currently don't need to use iwconfig or iw at all.
Modprobe I need in order to install the driver.
I've heard good things about wicd, but I've only
spent about 30 minutes (unsuccessfully) playing
