In case of system freeze, syslog might not get flushed to disk. Try using "sysrq" feature - this will allows emergency flush, getting backtrace etc. To enable sysrq echo 1 to /proc/sys/kernrel/sysrq then use ALT+sysrq+s for disk flush when system freezes. Maybe this will give something useful in syslog. (you can see other useful sysrq combinations at: http://en.wikipedia.org/wiki/Magic_SysRq_key) Also, I now have 64-bit Linux VM ready, so will try to repro too.
