'debconf-get-selections | grep grub-pc/install_devices' ?

Unfortunately this is not/set used by FAI, at least not by the scripts 
we use which may not be up to date.

According to the FAI logs this machine has been (re)installed with 
Squeeze roughly a year ago. The installed grub version was 
1.98+20100804-14+squeeze1.

I have only observed the problem on this particular box, but I did not 
do many Wheezy upgrades until now.

Cheers,
