yeah if this is what refit offers on the boot menu
screen i.g. apple logo, and tux/square logo(then some options);.

I'm thinking something is up with mbr grub/lilo(but could be wrong).
over here I do /usr/sbin/grub-install/setup /dev/sda*
which sets the mbr, so refit loads up, then loads grub(not sure with lilo);
keep in mind grub installs to /dev/sda3(root) for me, and not to a 
separate partition i.g. /dev/sda2(grub), and the /dev/sda3(for root, 
like what fedora does)

hope this helps.
