About DRI install and depmod problems

Dears:
        My  linux  kernel  is  2.4.18-3,  Xfree  is  4.3.0
        video  card  iss  Radeon  7500.
        i  download  DRI  binary  package  from  website  and  install,
          but  some  error  message  occurs  at  final  step,like  this:

Installing files:
         DRI XFree86 modules...done
         Kernel modules...depmod: *** Unsolved symbols in
/lib/modules/2.4.18-3/kernel/drivers/char/drm/radeon.o ... 
  done
         GL & GLU libraries...done
         core libraries...done
                 
         Update configuration:
             Running ldconfig...
             checking configuration...done

it  seems  radeon.o  has  some  symbols  problems,cause  kernel  can't  load  
it?
please  tell  me  how  to  solve  this  problem?
thanks  a  lot...
