Ok, my code was broken, but so was the original - the jogdial device 
isn't supposed to send scancodes for it's events:

         jog_dev->name = "Sony Vaio Jogdial";
         jog_dev->id.bustype = BUS_ISA;
         jog_dev->id.vendor = PCI_VENDOR_ID_SONY;
         key_dev->dev.parent =&acpi_device->dev;

         input_set_capability(jog_dev, EV_KEY, BTN_MIDDLE);
         input_set_capability(jog_dev, EV_REL, REL_WHEEL);

Note,  no EV_MSC, MSC_SCAN here.

Whoops, anoher bug!  Look there, it's setting key_dev->dev.parent 
instead of jog_dev.dev_parent!

I'll post a new patch when I've finished testing it.
