Hi Mauro,

Please cc: me on fbdev related patches (patch adding new FB_VIA
ifdefs _is_ definitely fbdev related).

This is incorrect (too simple), please take a look at FB_VIA entry:

config FB_VIA
       tristate =22VIA UniChrome (Pro) and Chrome9 display support=22
       depends on FB && PCI && X86 && GPIOLIB && I2C
       select FB_CFB_FILLRECT
       select FB_CFB_COPYAREA
       select FB_CFB_IMAGEBLIT
       select I2C_ALGOBIT
       help

Therefore you also need to check PCI, GPIOLIB && I2C dependencies.

* For PCI=3Dn:
