CONFIG_MEDIA_SUPPORT=y CONFIG_VIDEO_DEV=y CONFIG_DVB_CORE=y CONFIG_DVB_NET=y CONFIG_RC_CORE=y CONFIG_V4L_PCI_DRIVERS=y CONFIG_VIDEO_CAPTURE_DRIVERS=y CONFIG_VIDEO_BT848=y CONFIG_VIDEO_BT848_DVB=y CONFIG_DVB_CAPTURE_DRIVERS=y CONFIG_I2C_CHARDEV=y CONFIG_I2C=y I'm not sure if my 2 cards had eproms or not, but I did not require an extra options. However, I do know that when I first started using these cards many years ago, I initial had to use modules and some tweaks, but over the years the kernel drivers had improved to such a point where I could just statically build everything into the kernel.
