Good catch, I missed that file. After applying that patch, they now seem 
to be detected correctly:

da0 at mpt1 bus 0 target 0 lun 0
da0: <SEAGATE ST336732LW 2223> Fixed Direct Access SCSI-3 device
da0: 320.000MB/s transfers (160.000MHz, offset 31, 16bit), Tagged 
Queueing Enabled

The bad news is that any kind of extended disk activity (e.g. kernel 
building), results in a ton of unhealthy messages like this:

mpt1: time out on request index = 0xe4 sequence = 0x00000cad

Did I miss any more pieces? Nothing under sys/cam seemed recent enough.

Thanks,
