I believe that it (timerbench) is only needed for latency -t2, ICBW.
I built it as a module

Ive seen that Killed line before - but its been a while, I have no 
recollection...

have you tried 'run -- ' ?
the double dash insures that the following args are passed thru the script,
(so its very unlikely to matter here, but you never know ..)


heres a chunk from xeno-test on my box.
Obviously it didnt work for you, but you can re-try the running line,
see if its different than what youre currently getting.

FWIW, if you enable
CONFIG_IKCONFIG=y
CONFIG_IKCONFIG_PROC=y
then the xeno-test script will run that grep (ie zgrep XENO 
/proc/config.gz) for you.

there are a few additions that might be worthwhile -

 zegrep -E '^CONFIG_M|PREEMPT' pc-3/.config
CONFIG_MMU=y
CONFIG_MODULES=y
CONFIG_MODULE_UNLOAD=y
CONFIG_MODULE_FORCE_UNLOAD=y
CONFIG_MODVERSIONS=y
CONFIG_M586MMX=y
# CONFIG_PREEMPT_NONE is not set
CONFIG_PREEMPT_VOLUNTARY=y
# CONFIG_PREEMPT is not set
CONFIG_MICROCODE=m
CONFIG_MII=y
CONFIG_MSDOS_FS=m
CONFIG_MSDOS_PARTITION=y
CONFIG_MAGIC_SYSRQ=y

I havent made them, the CONFIG_M picks up the Machine, but is perhaps 
too noisy.
THen again, MMU an MODULE_* info is useful.
