Thumbs down Simple configuration? Changing regulatory domain of Wi-Fi

I think my main problem is I have no idea what the basics of Debian configuration are.
Continuation of this:
Reading this:
I felt it was more of a "Debian" issue, since I can't find any of the crda or db.txt on the system.
I have tried everything on that page. The udevadm didn't monitor anything after issuing iw set reg NL.
[kernel 2.6.32, wpa_supplicant 0.6.10, iw 0.9.19]
I tried searching the on-line Debian docs, but they seem awfully quiet about changing the region. Is it even possible? N.B. during installation I specified US region. I have tried changing the locales. No effect. I could try to reconfigure the wireless drivers, but I have no idea which package that is. Also I have no idea where wpa_supplicant actually looks for a configuration file. See? Lot's of Debian specific questions ;(
Any hints, tips, support, criticism appreciated... I'm desperate.

I would not expect locales to play any role in this (but I haven't actually checked).

% apropos regulatory
regulatory.bin (5)   - The Linux wireless regulatory database
% man 5 regulatory.bin
In that page there is a reference to the crda(8) man page which is in the crda package...

If this is not enough for you to go on, perhaps you could post a specific question.

Regarding wpa_supplicant, from reading /usr/share/doc/wpasupplicant/README.Debian.gz you can see that there it can either be configured in /etc/network/interfaces (Debian style) or you can configure it in much the same way as upstream. In general, checking for a README.Debian.gz (for any given package) is the first thing you should do if you want to find out something that you suspect may be Debian specific.

Thanks for the help. That's just the kind of info I was looking for.
I wrongfully assumed giving the kernel version would tell my distribution. It's Squeeze (Stable).
apropos regulatory Gives no output for me. I guess(?) crda is 'built' into the kernel in this distro, like mentioned on that page.
I have found /usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service thanks to that previous post.
Although it also mentions:
chmod 0600 /etc/wpa_supplicant/wpa_supplicant.conf
Where they finally specify the exact location of that file (that doesn't exist on my system yet). I can't find anything named nl80211 on my system, so I assume(?) it is using some older method.
I'm leaving the other thread open for the specific wlan question I had.
