Wifi is wifi, never heard of a wifi A or B.
actually, there's 802.11 (original, rarely used anymore), 802.11a, .11b. .11g. and .11n, and .11n comes in multiple flavors. Most everything these days is .11b/g or b/g/n compatible.
In various countries, there are different allotments of how many 2.4Ghz 'channels' are available for unlicensed use like wifi. see http://en.wikipedia.org/wiki/IEEE_802.11#Channels_and_international_compatib...
for a summary of this specific issue.
my general experience regarding all this is the business model laptops from the major makers (for instance, the Latitudes from Dell) tend to come with wifi (and modems etc) that support multinational standards that can be reconfigured for different locales. consumer grade stuff is less likely to have this ability enabled.
What i meant to say is that I have not heard of wifi thats strictly sort of regional. Most routers support all the major bands, and many laptops (as you pointed out) support those bands (abgn,..) Alternatively, a GSM router is all he needs, and his wifi enabled laptop would be happy either way, even if running centos.
