nforce3 support? mix&match rpms?

[Leon Bottou <leon@xxxxxxxxxx>]

Does the kernel support the nvidia nforce chipset?
Should we prefer another chipset to avoid playing 
with soon-to-be-available-binary-drivers?

Can we mix and match rhl9 and gingin64 binaries in order 
to have a mostly 32 bits system that is able to run 64 bits apps?   
Mostly scientific apps in my case.

I am thinking of installing rh9, replacing the kernel by the amd64 kernel,
installing the 64bit libs in /lib64 and /usr/lib64, and finally instally 
the 64 bit gcc.  Has this been tried before?
