[Centos] Digital IO card and /proc/devices

I have since upgraded to CentOS 3.4 and still no success. 
I had a look at the kernel code and there is a call to  register_chrdrv.
Could anyone tell me if that function is deprecated ?

The driver code is available from
ftp://ftp1.sealevel.com/pub/SOFTWARE/SEAIO/CURRENT/

Code snippet where the driver is registering with the kernel...

// Get the major number for the actual device node
                assigned_major = register_chrdev(major, "SeaIO", &seaio_fops);
                if (assigned_major < 0) {
                        PDEBUG(KERN_WARNING "SeaIO: can't get major %d\n",
                               major);
                        return assigned_major;
                        }

                if (major == 0)
                        major = assigned_major;
                #ifdef EXPERIMENTAL_INTERRUPT_SUPPORT_ENABLED
                // get the major number for the device's FIFO
                assigned_major_buffer = register_chrdev(major - 1, 
"SeaIO_FIFO",
                                &seaio_buffer_fops);
                if (assigned_major_buffer < 0) {
                        PDEBUG(KERN_WARNING "SeaIO_FIFO: can't get major 
%d\n",
                                major - 1);
                        return assigned_major_buffer;
                }
...
