The only thing I saw different between the dmesg output was from the 3.3rc7
[    5.937329] pata_jmicron 0000:03:00.1: setting latency timer to 64
[    5.946289] scsi8 : pata_jmicron.
[    5.970116] scsi9 : pata_jmicron
[    5.970501] ata9: PATA max UDMA/100 cmd 0xef00 ctl 0xee00 bmdma 0xeb00 irq 16
[    5.970503] ata10: PATA max UDMA/100 cmd 0xed00 ctl 0xec00 bmdma
0xeb08 irq 16

then you get
[    6.324507] ata9.00: ATAPI: LITE-ON LTR-48246S, SS0B, max UDMA/33
[    6.324511] ata9.01: ATAPI: LITE-ON DVDRW SHW-160P6S, PS0A, max UDMA/66
[    6.340507] ata9.00: configured for UDMA/33
[    6.372507] ata9.01: configured for UDMA/66
[    6.397218] scsi 8:0:0:0: CD-ROM            LITE-ON  LTR-48246S
  SS0B PQ: 0 ANSI: 5
[    6.419767] sr0: scsi3-mmc drive: 42x/48x writer cd/rw xa/form2 cdda tray
[    6.419770] cdrom: Uniform CD-ROM driver Revision: 3.20
[    6.419898] sr 8:0:0:0: Attached scsi CD-ROM sr0
[    6.419957] sr 8:0:0:0: Attached scsi generic sg4 type 5
[    6.427088] scsi 8:0:1:0: CD-ROM            LITE-ON  DVDRW
SHW-160P6S PS0A PQ: 0 ANSI: 5
[    6.429493] sr1: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray
[    6.429600] sr 8:0:1:0: Attached scsi CD-ROM sr1
[    6.429658] sr 8:0:1:0: Attached scsi generic sg5 type 5


On 3.3 I only get
[    3.231464] pata_jmicron 0000:03:00.1: setting latency timer to 64
[    3.255549] scsi8 : pata_jmicron
[    3.260534] scsi9 : pata_jmicron
[    3.260933] ata9: PATA max UDMA/100 cmd 0xef00 ctl 0xee00 bmdma 0xeb00 irq 16
[    3.260936] ata10: PATA max UDMA/100 cmd 0xed00 ctl 0xec00 bmdma
0xeb08 irq 16

Or thats how it looks to me
