[CentOS] Risks of installing i386 rpms on a x86_64 CentOS 4.4 installation

Personally I find that the best solution is to install an i386, then 
swapout the kernel, install a few extra 64 bit libraries, and then 
potentially reinstall whatever packages you need to be 64bit for 
performance reasons.

[Mind you, you might need to mess around a bit to get this working, I 
can't remember the exact steps I took last time I did this to get the rpms 
to install without complaints, but I think I remember actually doing both
a i386 and x86_64 install in seperate partitions and then doing a manual
merge and removing one of them... should probably document it...]

Me?  I use 32-bit everything, except kernel, libc, stdlibc++ and the 
compiler.  But then all I need it for is development of short but 
extremely memory hogging C/C++ applications.
