I owned CF-R7 decade ago, and running Linux was very enjoyable. No drivers were needed and almost everything worked.
The only thing that Linux lacked at the time was ability to turn on-off economy mode (at the time never seen that in laptops, it was to keep charge at 80% to extend battery life). I needed to boot to windows to switch that. And functional/multimedia keys although I was able to find software to get that to work.
