buisnesscard sid_d-i in "expert" mode asks different questions on amd64 vs powerpc

[Rick Thomas <rbthomas@pobox.com>]

I recently installed an AMD64 box from a sid_d-i businesscard CD in  
"expert" mode.
It asked me some questions that I didn't remember seeing on my PowerPC  
installations.

In particular, it asked me to chose a distribution (Lenny, Squeeze,  
Sid) and whether
I wanted to use non-free repositories.

I just did an "expert" mode install from the latest businesscard CD
on a PowerMac G4, just to be sure, and it did *not* ask me any such  
questions.

Is there some fundamental difference bewteen the two architectures  
that makes
this difference necessary?

Anybody know?
