Pretty same embedded system::
on a C3 1Ghz, 512 Mb of ram (256 for system memory and 256 in "ramdisk" 
to use /var and /tmp in read/write mode) and a 512Mb CF:
The way to minimize is like other distro: rm -rf /usr/share/doc :)

And of course, vanish yum, and install apt-get :)

You can slim a Centos to .. 300Mo, it's working fine and let you about 
215Mo for archiving and update features (glibc is the worst package to 
update :-/ )

At last, you can have a graphical desktop (xfce or a gnome desktop) in 
512Mo i think, but maybe the manpages will be delete too.
