Okay, the possible cause for the not working kernel for 770 is probably that the LCD controller is not an Epson Blizzard (S1D13744/S1D13745), but a S1D13742 controller. Luckily there's an OSS driver, I'll try to compile it. EDIT: It compiles, but has wrong header and the configuration executable doesn't support 770... So does anyone know where to find S1D13742.h with defines for 770's LCD controller? EDITx2: No need, its actually called hwa742 in the kernel config...
