Same here -- laptop is different (Averatec 3150H), but drive looks similar:

ATA channel 0:
    Master:  ad0 <IC25N030ATMR04-0/MOAOAD0A> ATA/ATAPI rev 6
    Slave:       no device present
ATA channel 1:
    Master: acd0 <UJDA740 DVD/CDRW/1.20> ATA/ATAPI rev 5
    Slave:       no device present

Last thing before hang with verbose boot (not necessary releated) is:

(probe0:ata0:0:0:0) error 22
(probe0:ata0:0:0:0) Unretryable error
(probe1:ata0:0:1:0) error 22
(probe1:ata0:0:1:0) Unretryable error

message is hand-transcribed because machine does not have serial port.

Let me know if additional details are needed or there are any patches to try.
