I am thinking of working on this in the next days and upload it to experimental. Last time I tried, I had some problems with the radeon kernel driver being loaded too late (see [1]). What do you use on Ubuntu in /etc/modprobe.d/ or on the kernel command line ?

I don't know the details how it is archived. Reason for putting radeon.ko to initrd is to get flicker free booting with splash screen. </div></div>
