Hint: You are trying to load a module without a GPL compatible license
      and it has unresolved symbols.  The module may be trying to access
      GPLONLY symbols but the problem is more likely to be a coding or
      user error.  Contact the module supplier for assistance, only they
      can help you.

/lib/modules/2.4.20-8/kernel/drivers/video/epiafb/epiafb_util.o: insmod epiafb failed
-------------------------------------------------------

modprobe加载模块的顺序是怎的呢？
我应该如何确定它们的依赖关系？
fb_info等在epiafb_driver.h中定义
read3CE等在epiafb_io.h中定义
