I've just read the comments of bug id 644898 (https://bugs.launchpad.net/ubuntu/+source/toshset/+bug/644898) and applied toshiba_acpi patch as described in the comments https://bugs.launchpad.net/ubuntu/+source/toshset/+bug/644898/comments/11 and https://bugs.launchpad.net/ubuntu/+source/toshset/+bug/644898/comments/13 .
Now freeze issue seems to be solved (at least it runs on battery over an hour). The reason why this bug appeared in new kernels of Ubuntu is described at this link https://lists.ubuntu.com/archives/kernel-team/2010-June/011112.html
