I made similar observations. My system is Intel 32 bit.
I decided to upgrade from 8.04 to 9.04 . For this I ran first the upgrade to 8.10 and than the upgrade to 9.04. I didn't have a look at the 8.10 system because I was keen on the 9.04 system so I started the upgrade to 9.04 just after the reboot after upgrade to 8.10.
Than I discovered that slapd wasn't installed in my 9.04 althoug it was in my 8.04 where it worked properly.
Than I tried to install slapd with synaptic and the error occured.
