You'll have to install madwifi driver. There are prebuilt rpms at
http://atrpms.net/dist/fc4/madwifi/

And if you want ACPI-suspend to work on T43 - you'll need the latest
kernel [2.6.12-1.1456_FC4] - and rebuild with the following patch:

[more info at http://www.thinkwiki.org/wiki/How_to_make_ACPI_work]

And In this case you are better off installing madwifi from source

- get snapshot from http://madwifi.otaku42.de/
- make
- make install
