Hi all ! ArthurDent, I'm using the CRJ with Ubuntu 10.04 64-bit and it's working fine, I just also had to install new 32-bit libraries. It's not a problem and X-Plane is my only 32-bit application. But if you manually install 32-bit libraries, make sure to install them in /usr/local/lib32 or /usr/lib32, because /usr/local/lib and /usr/lib are for 64-bit libraries. Best regards and happy flying. 8)
