Yes (this is why I wrote this message as a followup to the thread), all that was done in my first attempt, the problem is that the brain-dead firmware in this machine 
sees a GPT-partitioned disk and decides for itself that GPT = (U)EFI, and thus looks only for the EFI system partition, it does not try to boot from the gptboot in the freebsd-boot partition.
If I use a  MBR-partitoned drive, it boots ok.
And yes, the BIOS (sorry, UEFI firmware) is the latest that Acer has provided for this machine.

Just trying to make haeds and tails out of this UEFI thing, to see if it is a workable solution.
