I have a couple of SiI 3132 controllers (Masscool XWT-PCIE10) with
GPT partitioned disks, and the last sectors still appear to contain
the Sec GPT headers after several reboots.

I suspect your card's BIOS code.  You could see if your mainboard
has an option to not run expansion card BIOS code.  You could see if
there is a better version of BIOS code available for your card.

<KLUDGE>
If all else fails, you could create a backup copy of the last sector
and have dd(1) restore it from rc.local or cron @reboot.
