Thanks for this info. I have been doing some digging and it appears that 
both modules

/lib/modules/2.6.18-194.32.1.el5/kernel/drivers/media/video/video-buf.ko
and
/lib/modules/2.6.18-194.32.1.el5/updates/drivers/media/video/videobuf-core.ko


export the same symbol

nm 
/lib/modules/2.6.18-194.32.1.el5/kernel/drivers/media/video/video-buf.ko 
| grep videobuf_mmap_mapper
00000565 T videobuf_mmap_mapper

and

nm 
/lib/modules/2.6.18-194.32.1.el5/updates/drivers/media/video/videobuf-core.ko 
| grep videobuf_mmap_mapper
000002ac T videobuf_mmap_mapper

Which makes insmod puke

The former comes with the Kernel and the latter with V4L

I'll checkout your module-init-tools suggestion.

Thanks

Ken
