That took 25 minutes and reported the speed of 1.5x. The actual
command I ran was:
  time dd if=/dev/zero bs=1024k count=3000 | growisofs -Z /dev/scd0=/dev/fd/0

Seems that the burner alone is out of whack :-)

I haven't tried that yet. What I just noticed is that the
CONFIG_BLK_DEV_IDEDMA_PCI was not enabled in the kernel :-(
I am rebuiding the kernel, and hopefully this will allow me to set dma
to 1. I'll post the result here.

Thanks for your help,
Alex
