bttv driver and platform dependency

Dear all,

I build the source code of bttv (0.7.94) and insert the module successfully
on one platform (red hat 7.3 (kernel 2.4.18-3) + VIA C3 800 CPU). But when I
then try to insert the same binary module directly on the other platform
(red hat 7.3 (kernel 2.4.18-3) + P4 1.4G CPU), the system always shows a lot
of error messages like "unresolved symbol xxx" and fails to insert the
module. Does anyone has the same experience or know why? Thanks a lot!

Regards,
Kevin
