I've recently switched to 2.6 and now it says that using ide-scsi is obsolete. It also looks like the Cd-Writing howto which comes with Slackware 10.2 is outdated and does not cover these issues. I've still tried to write a CD (using ide-scsi) and the burning program started to write it at 0.1x speed
There's no need to spoon-feed me, just gimme some links where I could read about this and I'll come back with more specific questions if I won't be able to setup everything properly.
