I used Linux Rescue mode to free up /tmp. That allowed umount /tmp to proceed properly. However, parted would not resize /tmp because of some /tmp feature that is enabled: "Filesystem has incompatible feature enabled" (possibly dir_index, per web search).

Searching the web showed that this was going to be an involved problem, so I reverted to WinXP and used Partition Commander to resize the partition.

Linux reported /tmp as clean during bootup. DF -h reported the new size properly.
