Changes compared to 1.0.1-1:

- Split crda into crda and wireless-regdb (as it is done by all other
   distros that already include it)
   The regdb will probably be updated more often than crda
- If crda is installed, the integrity of the regdb is now verified on
   build and install time (if not, a warning is issued on build time, and
   nothing happens on install time)
   A warning is issued if the database is corrupted.
- The file /etc/conf.d/wireless-regdom moved from crda to
   wireless-regdb. If the user has already  set the domain there, the
   .pacorig file overwrites the one from wireless-regdb.
   This is safe, as the only changes that may be in the stock file are
   newly added domains, which are commented
- It is not necessary to add wireless-regdom to DAEMONS any more. As
   soon as cfg80211 is loaded, the regdom is set (if one is specified in
   /etc/conf.d/wireless-regdom)
   This is not only more convenient, but also ensures the regdom is still
   set correctly after rmmod cfg80211; modprobe cfg80211

Please sign off. Note that with 2.6.29-ARCH and newer, you will only get 
access to the "World" regdom (channels 1-11, plus some 5GHz channels 
with passive scanning only) if you don't install crda and set your 
regdom. (With 2.6.28-ARCH and older, the "US" regdom was enabled by 
default, and you could set "EU" and "JP" domains with a module parameter)

Signoff procedure:

1) If crda is already installed, wireless-regdb will issue a warning on 
installation if anything is corrupted. (You can also run regdbdump 
/usr/lib/crda/regulatory.bin manually, if that shows you a bunch of data 
instead of an error, all is fine).
2) After a you reboot, reload cfg80211 or "/etc/rc.d/wireless-regdb 
start", "iw list" should show you the proper channels. You will also see 
messages in your syslog if you change the regdom.

Pending issues:
Updates for BN (missing two 5GHz bands) and KR, see
http://permalink.gmane.org/gmane.linux.kernel.wireless.general/30811
DE domains misses some 5GHz bands due to confusing documents from the 
Bundesnetzagentur:
