To run 32 bit apps on 64 bit Linux, you need 32 bit versions of all the libraries the 32 bit app uses. It's like you've got 2 operating systems one 64 bit and one 32 - almost everything has been duplicated except a few things like the kernel.
It's actually a common problem for fonts to look different in 32 bit apps. It probably has nothing to do with Ati/AMD or their driver. It's caused by a mismatch between your 64 bit and 32 bit font rendering libraries, like freetype. They may be different versions, or compiled with different options enabled, or not sharing the same configuration file.
I suppose it's possible for the Ati control center to configure both. Maybe it's supposed to, I have no idea. It's probably a missing feature.
