here is the first problem - Jetway seems like to use Fintek SuperIOs now 
Coreboot has included F71805F/FG and the

J7F5M1G5E Board uses F71806F/FG or F71872F/FG (i think F71806F/FG because F71872F/FG has a Keyboardcontroller and the Board have no PS/2 Keyboard Port). I have found at Google that 71806 [3] and 71872 [4] (both supports 11 sets of voltage sensors) with are fully compatible (except the Keyboard Controller) [1], [2] and mostly(fully?) compatible with 71805 [5] (9 sets of voltage sensor).

Can anyone include this SuperIOs or can i try this with F71805? How i can change the Configuration from the VIA VT8454C to include this SuperIO (the rest must be identical)
- i think like the creation of Jetway J7F2/4 from VIA CN

Output of Superiotool: Found Fintek F71872F/FG / F71806F/FG (vid=0x3419, id=0x4103) at 0x4e
