Fedora 8 on PS3: ppc or ppc64?

[Andrea]

Hi,

I can't really understand whether the Playstation 3 running Fedora 8 supposed to be ppc or ppc64.

The question arises because it seems that it is not possible to install both RPMs for ppc and ppc64 
for all application.

For instance: I cannot install alsa-lib-devel for both because they provide the same documentation 
files that conflict.

The same for gdb-ppc and gdb-ppc64. I have both RPMs installed, but gdb is in the same path for 
both: /usr/bin/gdb and only the last survives, the first is overwritten?

Am I wrong?
