[SOLVED] How to create a wlan0 interface?

Question

Hello:
I'm getting a lot of problem with my wireless card, as you can see in this post (unsolved).
I installed the supposedly driver for my wireless card without result. Installed "WICD" -installed networkmanager, but never achieved to initialize the GUI- and just see my wired connections, not the wireless, mine or from others.
I'm just wondering if the problem is that I do not have a "wlan0" interface in my "/etc/rc.conf". If that  is true, could I create one by myself? In the wiki there are many pages (wireless setup, beginners guide, etc) that makes some dispersion in the information and it is difficult to me to follow -and evaluate- That's why I'm asking for your support.
My actual rc.conf -selected parts- is -notice that because WICD there are some "!", as the wiki suggested -:
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
#Static IP example
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
INTERFACES=(!eth0)
# DAEMONS
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background
DAEMONS=(syslog-ng dbus !network wicd netfs crond alsa hal sensors privoxy tor)
ifconfig -a

Should I create a wlan0 interface? How?
Thank you very much.
PD: I also create a WPA profile in netcfg, following the wiki, but it is not working. I get:
> Profile "mynetwork" does not exist (but I created it!!!)

I know this is not what you expect as a reply but anyway... I recently bought a very nice machine which is a Thinkpad x201i (the cheap version of the x201), great build quality, affordable price, perfect size and enough processing power. The problem is that it came with a realtek 8192se wireless card. It's everywhere on the internet: the driver sucks and it's only supplied by the vendor (so not in kernel tree, not even in staging). it costed me few bucks and 20 minutes of my time to replace it with an intel centrino advanced 6200N, I guess the Intel Centrino-N 1000 is even cheaper (saw it at less than USD15 on amazon). You'll get in-tree kernel drivers, injection support and all that fun stuff... I was happy to pay the extra money just thinking about the endless frustration I would have gotten with the realtek card. Not that compiling a driver makes me scared, but using a crappy driver is a pain.
