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
   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
DE domains misses some 5GHz bands due to confusing documents from the
