It would be nice to be able to add a short string to the kernel version
for identification, to differentiate between runs with the same kernel and
different tuning.
I've found that tuning often helps response, like reducing memory with
older rmap versions (ran for a while using mem=256m), or tuning bdflush
with -aa kernels, which I did after Andrea gave me some serious hints.
Just a short string added to the version would make this a bit easier to
follow after the fact.

Easy fix. Will do. The original version you had to tell it which kernel you were
running so I can add that as optional.

Perfectly reasonable. Be aware though that reducing mem will also change the
write size of io loads in contest. Although this will test the VM's response to
half and full size writes it will also decrease the size of IO load.
