SubjectFast DMA CD audio extraction

I'm trying to get decent performance (e.g. DMA, not PIO) extracting audio with
cdparanoia from an new IDE CD-ROM. The current problem is very slow ripping
and very high system CPU time. hdparm reports DMA is on, and reading data is
perfectly fast.

What kernel versions and patches should I be trying?

(Please cc: me, emailing in reply to linux.kernel posts munges threading)
