GEOM is too verbose

[Maxim Sobolev]

Hi Poul,

I use application that detects size of disk using binary search. On 
current each attempt to read beyond disk boundary causes message on 
console, which is annoying. Can you please turn them off, since 
apparently they serve no meaningful purpose.

Thanks!
