I've found out what went wrong. I boot the Ubuntu installation DVD,
from an USB stick. In the boot menu of the motherboard, there are,
amongst many others, the two entries "USB: Verbatim 8.07" and "UEFI:
Verbatim 8.07".

So far, I've used the "USB: ..." one. Now I've tried out "UEFI: ...",
and the problem went away. Now the installer makes an UEFI System
Partition, an entry in the motherboard's boot menu, and gdisk doesn't
complain about a broken partition table any longer. The new system can
be booted.

Cheers
