no. it does not report just FSB speed, it reports the speed at which that 
specific chip is running. 266mhz means the *frequency* is 266mhz. which 
means, since it is ddr, it is doing '2100 megabytes per second'.

if you want to know what the chip is physically capable of (on-chip info),
run decode-dimms.pl (part of lmsensors)
