An air carrier pilot reports exceeding 250 KTS on the gorman (gmn) four departure prior to ATC's normal speed clearance. Reporter states that chart format and fatigue were factors.

Narrative:

Passing through 10000 ft MSL on gmn 4 departure; FMS commanded acceleration to 325 KIAS. Through approximately 11000 ft MSL on initial contact on frequency change we were told to '...resume normal....' no other comment was made by ATC but; on review of SID; one of the notes specifically said 'maintain 250 KTS unless otherwise directed by ATC.' indicated airspeed was approaching 300 KIAS at the frequency changeover. Lack of attention to detail aggravated by some fatigue from circadian disruption was the primary cause of this error. FMS complacency and SID narrative located in different sections were lesser secondary causes of this error. More attention to detail and further recognition of circadian related issues are what I have to do to prevent future errors.

Title: AN ACR PILOT REPORTS EXCEEDING 250 KTS ON THE GORMAN (GMN) FOUR DEP PRIOR TO ATC'S NORMAL SPEED CLRNC. RPTR STATES THAT CHART FORMAT AND FATIGUE WERE FACTORS.

Narrative: PASSING THROUGH 10000 FT MSL ON GMN 4 DEP; FMS COMMANDED ACCELERATION TO 325 KIAS. THROUGH APPROX 11000 FT MSL ON INITIAL CONTACT ON FREQ CHANGE WE WERE TOLD TO '...RESUME NORMAL....' NO OTHER COMMENT WAS MADE BY ATC BUT; ON REVIEW OF SID; ONE OF THE NOTES SPECIFICALLY SAID 'MAINTAIN 250 KTS UNLESS OTHERWISE DIRECTED BY ATC.' INDICATED AIRSPD WAS APCHING 300 KIAS AT THE FREQ CHANGEOVER. LACK OF ATTN TO DETAIL AGGRAVATED BY SOME FATIGUE FROM CIRCADIAN DISRUPTION WAS THE PRIMARY CAUSE OF THIS ERROR. FMS COMPLACENCY AND SID NARRATIVE LOCATED IN DIFFERENT SECTIONS WERE LESSER SECONDARY CAUSES OF THIS ERROR. MORE ATTN TO DETAIL AND FURTHER RECOGNITION OF CIRCADIAN RELATED ISSUES ARE WHAT I HAVE TO DO TO PREVENT FUTURE ERRORS.
