Seems to work well.

The only outstanding issue I have is with the "Generic ATA support" option which 
I believe should be detecting and driving my ATA DVD-RW.  However it is giving 
this still on boot - it has never worked:

And no DVD-RW :-(

I posted some information about it to LKML on 10/07/06

  ATAPI CD-ROM, with removable media
         Model Number:       PIONEER DVD-RW  DVR-111D
         Serial Number:      FADC005671WL
         Firmware Revision:  1.23
  + more

but had no feedback.

Should I continue to ask/report it or should I just disable it for now and try 
again in a few months to see if it works?
