gbuffers is only valid in bttv.  To increase the number of buffers in 
bttv2, increase bttv_maxmem (default is 8).  This tells the driver what 
the maximum amount of memory (in megabytes) is to allocate capture 
buffers.  I usually load bttv2 with bttv_maxmem=32 (which gives _lots_ 
of buffers ;-) ).
