video-buf.o vmalloc_to_page error

[Jon <jon@xxxxxxxxxxx>]

I'm using kernel 2.4.19pre8-ac5 with all of the appropriate patches
installed from bytesex.org/patches the module (from the bttv-0.8.40
package) compiles fine, but gives me this error when I try to insmod
video-buf.o (a dependance of bttv.o)

video-buf.o: unresolved symbol vmalloc_to_page

If you have any suggestions please let me know...

Thanks,
jon
