Don't know, but the media I'm using is TDK Data CDR rated to 52X. I'm
sure the problem is more with my drive than the media. My point is
that until you get the right combo via trial and error, it's dangerous
for an application to assume it can burn at the highest-rated speed.
I couldn't use NTi Backup Now for that reason since it tried burning
at some speed over 4X on my system and turned out a coaster every two
or three CD's - making it useless for backup purposes.

IS the burn speed passed to cdrecord or isn't it? And is it
specifiable at the user level? I don't want an application deciding
burn speed for me without the ability to override it.

Operative word is "should". I'm not using k3b at the moment so all
I'm saying is until someone proves it's smart about how reliably it
can burn given a specific media and drive, there should be a way to
specify an override.

Exactly. Which is why you need to be able to override it.

Well, as to the latter, my Kongueror on Red Hat 7.3 crashes about
three or four times an hour. It's definitely going to get upgraded to
a newer version soon.
