Yeah, the M952 was the only MTB bottom bracket with the V1 format that also fit most of Shimano's Octalink road cranks. And yes, the BB5500/BB6500 road bottom brackets only came in 109.5 and 118.5 l(double and triple) spindle lengths. Your best bet is E-bay and I found several listings for the correct M952.
BTW, surreal is incorrect. Octalink may be obsolete but it was a decent interface and the durability was good.
