That is by upstream's design, /var/log is on a tmpfs and its contents
are lost on a reboot.

Good to hear, did you have any issues during playback?

I get a funny feeling that the FSP fix that went into olpc-utils needs
to be re-run after a suspend/resume cycle. Powerd has a build-in
workaround for the original ALPS touchpads, but I think I could run
'/usr/bin/olpc-fsp-regs set' from powerd's postresume hooks.
