Well, the dependency is pretty clear, cdrecord doesn't have a say as to
what the kernel does or leaves. It's not like a newly released kernel
would run instantly on 50% of the Linux systems, it usually takes a few
month until it hits the distributions.

You're asking too much here. At the time the change was introduced, all
that was needed was adding /dev/hd* to the scan list and the LF_ATA
workaround (BTW, you still haven't explained what LF_ATA inside libscg
is good for, I asked many days ago).

It's good that you only attribute "experienced" and not other
adjectives to yourself here. One might otherwise get the idea you were
boasting with the scarcely documented code...
