"So what does that mean for you? Well, you have to decide for
yourselves. Since I have multiple external DVD devices I still stick to
kernel 2.6.7 since otherwise I would always have to make sure the tray
is not open when starting K3b and trying to burn something. But if you
don't have any external devices and configure cdrecord properly using
kernel 2.6.9 should be no problem."

I just did a test burn on my system to be sure not telling you nonsense.
I have FC2 all up2date (2.6.9-1.6_FC2smp,cdrecord-2.01.1-0.FC2.1,
k3b-0.11.14-0.FC2.2) and an internat ATAPI CD-RW burner by Plextor. No
external hardware. I just did erase a CD-RW media with k3b without a
problem. Following is the output of using cdrecord to burn an ISO image
file on the blanked media:

$ cdrecord -eject OpenBSD36-i386.iso

Though the process spits out a lot of warnings, the CD-RW is properly
burned. Of course it is done as normal, non-root user.
