Not sure if this is your exact issue, but it may help anyway.
To get the FB module inserted whenever you install a distro kernel,
create /etc/sysconfig/mkinitrd with contents:
MODULES="radeonfb"
Put any module options in /etc/modprobe.conf before rebuilding the
initrd.
I use the radeonfb on my Thinkpad to deal with a suspend power issue,
and those two steps work for me.
