As I understood the isolcpus=1 (for a dual core processor) is "mandatory" . I you have multiple cores 4 or 8 (but you shouldn't) there is a different isolcpus setting to optimize the RTAI results (aka latency). Have you tried to let the GPU drivers as the installation process load automagically. I do believe that 1GB RAM maybe is the lower limit to get the new installation working properly. I'm not an expert so sorry if I'm not so effective on helping you. ;-)
