This is a bit brain-dead ...

You should be able to 1)get the index with INDEX, 2)do some math with the 
index, then 3)use CHAIN to get back:

hwLswFrameIndexIndex : INDEX {hwLswFrameIndex} # 0,1,2 ....
hwLswFrameIndexMatch : MATH : ({hwLswFrameIndexIndex} +1) x 65536 # 
65536,131072

hwCpuCostRateFrame : CHAIN {hwCpuCostRate} {hwLswFrameIndexMatch}
hwMemFreeFrame : CHAIN {hwMemFree} {hwLswFrameIndexMatch}

Now you should have something like this:
hwCpuCostRateFrame.0 = Gauge32: 84
hwCpuCostRateFrame.1 = Gauge32: 59
hwCpuCostRateFrame.2 = Gauge32: 57

hwMemFreeFrame.0 = Gauge32: 41651576
hwMemFreeFrame.1 = Gauge32: 35982132
hwMemFreeFrame.2 = Gauge32: 36261272

You may want to use devmon from svn for this, I think there were some small 
bugfixes in the INDEX operator.
