I should add:

+++ firegl_public.c	2006-06-26 11:49:18.010773318 +0200
+/* MODULE_PARM is obsolete */
+#if  LINUX_VERSION_CODE < KERNEL_VERSION(2,6,16)
+ MODULE_PARM(firegl, "s");
+#else
+ module_param(firegl, charp, 0400);
+#endif

No, you should remove 


MODULE_PARM(firegl, "s");

and then add 

/* MODULE_PARM is obsolete */
#if  LINUX_VERSION_CODE < KERNEL_VERSION(2,6,16)
 MODULE_PARM(firegl, "s");
#else
 module_param(firegl, charp, 0400);
#endif



the +++ firegl_public.c     2006-06-26 11:49:18.010773318 +0200 is for the patch program to know what file to patch.
