On cards which do not support it, LFB can be simulated by trapping page faults and, if the fault address is within a specific range, setting the frame buffer window origin correctly and mapping it into memory so that the instruction which caused the fault, once restarted, will succeed. It's a hack and it's probably slow as hell, but it works.
