(Just sending this out there in case anyone is interested. If you have a better way, pass it on...)

rpm can provide you with the name and architecture when querying the installed rpms.

Typically rpm -q filename will only tell you it is installed, but not which architecture(s).

[root_at_rac2 /etc]$ rpm -qa glibc

glibc-2.5-81
glibc-2.5-81

To get the ARCH you can use --queryformat '%{NAME}-%{VERSION}-%{RELEASE}-%{ARCH}\n'

[root_at_rac2 /etc]$ rpm -q --queryformat '%{NAME}-%{VERSION}-%{RELEASE} %{ARCH}\n' glibc
glibc-2.5-81 x86_64
glibc-2.5-81 i686

To make this simpler, you can create (or add) an alias to /etc/popt, or ~/.popt:

rpm     exec -q                 rpmq -q --queryformat '%{NAME}-%{VERSION}-%{RELEASE} %{ARCH}\n'

Take a look at /usr/lib/rpm/rpmopt-{version} to see a horde of aliases that rpm uses to get an idea what's available.
