Only characters are mirrored, and not the entire row (ie, row starts at the left
side, and not at the right)?

Can you try fbset -accel false and see if it helps?

If it does, this is a problem with nvidia's imageblit function which converts
big-endian bitmaps to little endian?  Perhaps the help reverse_order() is not
needed for your arch.  Can you comment out calls to reverse_order() in
drivers/video/nvidia/nv_accel.c?

I think rivafb supports this particular chipset, but without acceleration.
