Hi there, Why don't you look for it in the kernel source code? Type `make menuconfig` and go to Devvice Drivers -> Graphics support -> Support for frame buffer devices.
Then according to the config item, go to `drivers/video` and find your fb driver by the Makefile. But according to your problem description it may not be the same issue as mine. There's not much I could help.
