patch to prevent nvclock segfaults on amd64

[tony mancill <tony@mancill.com>]

For anyone using NVidia who would like to tweak card settings, here's a 
simple patch for nvclock:

--- nvclock-0.7.orig/src/backend/nvclock.h
+++ nvclock-0.7/src/backend/nvclock.h
@@ -78,7 +78,7 @@
    char *card_name; /* Name of the card */
    short supported;
    short device_id;
-    int reg_address;
+    unsigned int reg_address;
     char *bus_id;
     short base_freq;
     gpu_type gpu; /* Tells what type of gpu is used: mobile, nforce .. */


The patch has been submitted to the Debian BTS as a follow-up to #276451. 
Is it permissible/helpful to prepare and upload an NMU to alioth?

Cheers,
tony
