Bah, nvidia chipset :)

Try changing line ~478, replacing "nVidia" with "VGA compatible controller":

@@ -475,7 +475,7 @@ We need to look through it to find the smaller region base
address f8fffc00.
        if(fgets(line,sizeof(line),fp) == NULL) {  /* if end of file */
           fatal("Radeon hardware not found in lspci output.\n");
        }
-       if(strstr(line,"nVidia") || strstr(line,"nVidia Corp")) {  /* if line
contains a "radeon" string */
+       if(strstr(line,"VGA compatible controller") || strstr(line,"nVidia
Corp")) {  /* if line contains a "radeon"
           if(skip-- < 1) {
              break;
           }

then re-run make and try again
