UMMM ... that would be because the people who made the card made it to
work on Windows ... they did not make it to work on Linux.  They don't
provide technical specs or free software drivers so some poor smuck sets
in a room and reverse engineers a driver for it.

Obviously a reverse engineered driver is not the same as a hardware
driver programed by the manufacturer.

Red Hat has ipw2200 and ipw2100 drivers that are not free and have no
SOURCE ... but if you are a paying client you can to get them.  Those
drivers and firmware are not free or re-distributable by CentOS.

If running your wireless on Linux is important to you, complain to the
laptop manufacturer so that they will put in devices that support linux
properly out of the box.
