Ok, did it like described, strange but the ksyms look still the same:
(wonder if that GPLONLY is the problem?)

ccbe0060 GPLONLY_videobuf_vmalloc_to_sg [video-buf]
ccbe01ec GPLONLY_videobuf_lock  [video-buf]
ccbe028c GPLONLY_videobuf_unlock        [video-buf]
ccbe02e0 GPLONLY_videobuf_dma_init_user [video-buf]
ccbe0408 GPLONLY_videobuf_dma_init_kernel       [video-buf]
ccbe0490 GPLONLY_videobuf_dma_pci_map   [video-buf]
ccbe05bc GPLONLY_videobuf_dma_pci_sync  [video-buf]
ccbe05ec GPLONLY_videobuf_dma_pci_unmap [video-buf]
ccbe063c GPLONLY_videobuf_dma_free      [video-buf]

<OT>
Another thing - once the version information was for the reason that one can 
use modules compiled for ealier kernelbuilds without recompiling - is that 
feature gone now?

Why get all my other drivers deleted if i rebuild kernel?
</OT>
