Exactly which patches did you apply? My ia64 development system only has
the symbols which should be there.

0000000000000020 ? __module_author
0000000000000068 ? __module_description
0000000000000000 ? __module_kernel_version
0000000000000000 g __module_usb_device_size
0000000000000008 g __module_usb_device_table
                 U __this_module
