I do not beleive using a GC for these roles is neccesary and in some cases I
know you do not want the PDC Emulator on a GC like if you have child
domains.
.
I believe that the role in question would be
Infrastructure Master....not PDC Emulator...unless all of
your DCs are also GCs...
There are two Forest-Wide roles ( Schema Master and Naming
Master ) and there are three Domain-Wide roles ( PDC
Emulator, RID Master and Infrastructure Master ).
If you have yourdomain.com, child01.yourdomain.com and
child02.yourdomain.com then you would have a total of 11
roles ( the two Forest-Wide roles and then three sets of
the three Domain-Wide roles ).
The role of the Infrastrucutre Master is to keep track
of "phantoms". A "phantom" would be a member of another
domain that is in a group in your domain.
Let's take yourdomain.com, for example. Let's say that
you create a Universal Security Group called FINANCE. It
contains a Global Security Group from yourdomain.com,
child01.yourdomain.com and child02.yourdomain.com. Each
of these Security Groups has as members every user account
in the Finance Department in it's respective domain.
Furthermore, all of the user acocunts in each domain are
located in the OU called Finance. Let's say, for example,
that in child02.yourdomain.com you had to move half of the
user accounts to a sub-OU called Finance Assistants.
This is where the Infrastructure Master comes in...It is
its responsibility to know that those users were
moved...and to where.
Does this help?

PS...generally you want to keep the PDC Emulator and RID
Master roles on the same DC if you are going to have
different FSMO roles on different DCs...
