add basic support for ag241 ar7 based dsl router

- my wag54g died. disable wag54g for now.
- add 2.6.32 support for ag241.
- cpmac still broken

+ * Support added for the new WRT54G v2.2 and WRT54GS v1.1 "flags"

+ * 
+ * Extensions:
+ *  -{0|1|2} sets {0|1} sets hw_ver flag to 0/1. {2} sets hw_ver to 1
+ *     and adds the new hardware "flags" for the v2.2/v1.1 units

+ *
+ * AG241V2 firmware sets the hw_ver to 0x44.

+ * Example: -r 2.0
