AHA! Currently, writing only works as root with that kernel. You /can/
make it work by uncommenting one or two lines in the sources and
recompiling the kernel. That will omit the new security checks and act
like 2.6.7 did. In my opinion better that using 2.6.7, because that one
had several security problems that have been fices with 2.6.8. There
was a small patch posted to LKML, but I cannot find it right now. Maybe
you google around a little under the groups search in linux.kernel.

No. In fact, using ide-cd and the new system is the only way I know to
get DMA working both for reading /and/ writing CDs with blocksizes
other than 2048, e.g. Audio CDs.
