An air carrier Captain reported executing a go-around after encountering wake turbulence landing behind a B767 on a closely spaced parallel DFW runway.

Narrative

11000 FT on BOWIE 9 STAR @ 270 KIAS into DFW. Slowed again and turned off course to allow traffic to go ahead of us. We were cleared behind them 7 NM to 5000 FT and encountered the B767 heavy wake turbulence. This was reported to ATC; we were at 250 KIAS as per STAR. A stern; annoying dark voice came on (supervisor?) and we were instructed to maintain 210 KIAS and expedite to 5000 FT. B767 was cleared to land Runway 18L; which is normally the takeoff runway on west side at DFW. Landing Runway 18L is shorter taxi to gate. ATC was expediting flight into DFW -- ok with me; but at our 67 passenger's expense and we were already 1 hour late; too. Passengers were going to miss connect (and it is not the safest operation to mix takeoffs and landings on same runway). We were cleared for visual approach Runway 18R with winds 080 @ 6 KTS. At less than 100 FT AGL we encountered B767 wake turbulence (even with flying high on glideslope); and had to go around. Its turbulence had drifted onto our runway. 10 minutes later we landed on Runway 13R. Not safe!!
