Yes it is a Titanium Omega Stealth Frame that Michael Hutchison rides, Sean Yates also Used one last year and is presumably using one again this year.
Stuart Dangerfield who has often been been Hutchinson's nemisis on the UK time trial scene did use a round tube steel frame to win numerous time trial comps over here http://www.argoscycles.co.uk/history.htm . I think for the last Olympics he was given one of the BCF's Carbon bikes other wise he probably would have used one there. I believe in 2001 he broke the 10-miles competition record with a time of 18'19" (32.76 mph), which is quite useful as is his 25mile pb of 47.47.
