The good parts - no Oops, no process stuck in "D", tha bad parts - it didn't work:-), the IDE LED stays on and I cannot eject the CD. The CD-R is a BenQ 52x32x52 Seamless Link alone on ide1, the disk does indeed say 4x-10x. The cd-writer works mostly... if I am gentle to it - I usually burn at 32x even if the media says 52x... Is it just a hw-failure or a driver bug?
