The ECP direction: reverse messages are just the kernel telling you it
is doing a read.  The low frame rate is also normal right now.  I'm
assuming it is beacuse the FIFO and DMA are unused.  I plan to look into
this and hopefully get a patch into parport_pc before the 2.4 kernel is
released.  I don't know why gqcam is hanging, are there any messages in
the logs?
