there isn't any 10GE OSM but there are certainly 10GE modules for the 6500/7600 with deep buffers.
most recently, Guido Appenzeller, Isaac Keslassy and Nick McKeown have written a paper that they presented at SIGCOMM 2004 about "sizing router buffers" that is very informative and goes against the grain of the amount of buffering required in routers/switches.
for folk who aren't aware of some of the hardware limitations faced today, the paper provides a fairly good degree of detail on some of the technical tradeoffs in router/switch design and some of the technical hurdles faced by ever-increasing interface speeds today.
while Moore's law means that the processing speeds get faster and faster, the same amount of innovation cannot be said for either speed-of-RAM or chip packaging, which have fallen significantly behind both Moore's law and speed-of-interface growth curves.
NB. not speaking for my employer, this is an area of research that is of personal interest to me. but of course, my employer spends a lot of time looking at this.
