I pieced together how to update a ThinkPad's ME firmware without Windows last week: https://news.ycombinator.com/item?id=15744152 https://news.ycombinator.com/item?id=15744152 - the process is a pain, as Lenovo only provides a Windows binary for installing the update, so you have to piece together a WinPE image that contains the ME driver and firmware update tool, boot it, load the driver, and then execute the firmware update. The process is probably the same for most other vendors, so if your vendor provides a Windows ME firmware updater (no pun intended :P) you might be able to make it work that way.
