packet-cd for 2.4.27-pre6+

(Since I feel lazy these days, I'm asking without trying anything first ;) What changes are needed (if any) for packet-cd to be applied to kernels 2.4.27-pre6 onwards, since Jens applied DVD-RW support ? Especially, what is the fate of those patches in the "extras" directory? Regards, Özkan Sezer
