More a note to self than anything else for how I got FC6 working on my Thinkpad R51
For – kernel panic: Cannot execute a PAE-enabled kernel on a PAE-less CPU!
Do not choose virtualization during package selection and for a good measure select Legacy Support.
For – ipw2200 wifi not detected
Download latest V30 firmware from http://ipw2200.sourceforge.net/firmware.php unzip it and copy the files to your /lib/firmware directory and reboot.
