The problem had been resolved.
There is an old LINUX_VERSION_CODE in the version.h. So i clean the
kernel tree and make a full compile again. The errors above went away.
Another thing is i found the latest compat driver contains some
graphics drivers. When i install a wireless driver, such as b43, the
graphics drivers also will be installed. That will break my original
in-tree graphic drivers dep and caused some issue when X startup.
So now, i turn to use latest wireless and graphic in-tree drivers with
the latest kernel. They work well.
Thanks, again!
