CentOS - Jul 2011 - CentOS6: installing 32bit and 64bit RPMS via the installer?

Installing 64bit CentOS6 only installs x86_64 and noarch RPMS - however, 
I have a number of legacy 32bit apps that require a number of 32bit RPMS 
to be installed.

Does anyone know how to get the installer to install the 32bit versions 
of 64bit RPMS? i.e. in the way it does for CentOS5.

Thanks

If you use a kickstart, you can specify packages with a specific arch:

? %packages
? glibc.i686
? %end

After and bit of digging, it appears to be down to a change of a default 
setting in yum with CentOS6

The yum config option multilib_policy is now 'best' in CentOS6 - in 
CentOS5 it is 'all' - which means CentOS6 will only install the x86_64 
version if both a x86_64 and i686 RPM exists in the repo

I guess if I want to revert this back to 'all', I'll need to hack 
anaconda to add 'multilib_policy=all' to the temporary yum config file.
