I applied this patch to 2.6.24-rc7. Now at boot time my DVD-RW is
normaly detected as:

sr0: scsi3-mmc drive: 48x/48x writer dvd-ram cd/rw xa/form2 cdda tray

But I cannot mount it. All my attempts failed with

ISOFS: Unable to identify CD-ROM format.

With mem<=4098M or sata_nv.adma=0 it still mounts and works ok.
