There are some differences, but nothing insurmountable.
For <=2.4 you have to include Rules.make at the end of your own Makefile,
and for 2.5 that file doesn't exist any more.
For older kernels you must set O_TARGET, for 2.5 I think the mere act of
setting it causes the build to break -- that one is gratuitously making it
harder to make external modules which compile in both and I've complained
about it before.
Per-file CFLAGS must have a full path specified now in 2.5, whereas in 2.4
and earlier it was just 'CFLAGS_filename.o'.
