Care to send a patch? Download
http://git.kernel.org/?p=linux/kernel/git/linville/wireless-regdb.git;a=blob_plain;f=db.txt;hb=HEAD and edit as appropriate.

As you can see in the rules for DE, you can give the values in mW too:

        (2400 - 2483.5 @ 40), (N/A, 100 mW)

I encourage you to add a comment, so that the CZ entry looks like this:

# Data from
# http://www.ctu.cz/1/download/Opatreni%20obecne%20povahy/VO_R_12_08_2005_34.pdf
# and http://www.ctu.cz/1/download/OOP/Rok_2007/VO_R_10_03_2007_4.pdf
country CZ:
	(2402 - 2482 @ 40), (N/A, 20)
...
	(5250 - 5350 @ 40), (N/A, 200 mW), NO-OUTDOOR, DFS
etc.

Hmm. I don't think we have a way to capture this right now, should
probably use the lower values then.
