Yes, you are doing it exactly right.

I see:

Block layer SCSI generic (bsg) driver version 0.4 loaded (major 253)

ata1: PATA max UDMA/100 cmd 0x1f0 ctl 0x3f6 bmdma 0x1460 irq 14
ata2: PATA max UDMA/100 cmd 0x170 ctl 0x376 bmdma 0x1468 irq 15

Indicates to me that the hardware is seen.

scsi 0:0:0:0: CD-ROM    SONY     DVD-ROM DDU1621  S1.6 PQ: 0 ANSI: 5
sr0: scsi3-mmc drive: 16x/40x cd/rw xa/form2 cdda tray

It definitely sees the CD-ROM

Detecting Adaptec I2O RAID controllers...

I don't know waht your partition values would be, but I always like to 
use root=/dev/sda3 (or whatever is right)

It's not clear which booted system the dmesg is from, but it looks like 
the one you posted found the disks.  I don't think I can help any 
further, but it really looks like a driver problem to me.
