It will not work :(
I had same problem and this strange behaviour can be suppressed with
vqmin=2 and vqmax=9 in -lavcopts.

Example:
1st pass (audio) done
2nd pass (1st video)
mencoder source -oac copy -ovc lavc -o /dev/null -lavcopts 
vcodec=mpeg4:vhq:vbitrate=1835:vqmin=2:vqmax=9:vpass=1
3rd pass (2nd video)
mencoder source -oac copy -ovc lavc -o dest.avi -lavcopts 
vcodec=mpeg4:vhq:vbitrate=1835:vqmin=2:vqmax=9:vpass=2

maybe in 3rd pass vqmin=2 and vqmax=9 is needless (values are taken from 2nd
pass text file), but I'm lazy edit whole line in shell history and this works
too :).

With this options, the encoded file's bitrate have exact desired value.

I will definitely try using vqmax=9 next time.
