That isn't true. OSR is nothing more than an old product name for a 7609
chassis bundled with a SUP2/MSFC2. Cisco ditched this scheme when they 
started pushing the SUP720, in favor of just describing the chassis and 
sup with different part numbers. There is absolutely no such thing as an 
"OSR" chassis, a 7609 is a 7609 is a 7609. What you're actually refering 
to above is the SUP2/MSFC2 support, which has nothing to do with the 
chassis. After you replace the sup with a SUP720 or RSP720 it will run 
SR/SXH just fine.

The two major caveats for putting SUP720 into an older chassis which 
originally shipped with SUP2's (and this applies to 6500 just the same) 
are:

a) In the 09 you need a 2500W power supply (old 1300W's which were 
common with sup2's work work)

b) You need to upgrade to a high speed fan tray (which goes by many 
different part numbers depending on the chassis, 6509-NEB-UPGRD is 
indeed the correct fan for the old classic 7609).

After that, it will run whatever you'd like.
