I added "hw.ata.atapi_dma=1" to /boot/loader.conf and rebooted. Now I 
got UDMA33 on primary slave, too. Other than that, the output of dmesg 
is basically the same, but the devices were probed (?) twice:
$ dmesg | grep -e ^ata -e ^ad -e ^acd
atapci0: <Intel ICH2 UDMA100 controller> port 0xfc00-0xfc0f at device 
31.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]
ata1: at 0x170 irq 15 on atapci0
ata1: [MPSAFE]
ad0: 29325MB <Maxtor 6E030L0> [59582/16/63] at ata0-master UDMA100
acd0: DVDROM <LITEON DVD-ROM LTD-165H> at ata0-slave PIO4
atapci0: <Intel ICH2 UDMA100 controller> port 0xfc00-0xfc0f at device 
31.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]
ata1: at 0x170 irq 15 on atapci0
ata1: [MPSAFE]
ata0-slave: DMA limited to UDMA33, non-ATA66 cable or device
ad0: 29325MB <Maxtor 6E030L0> [59582/16/63] at ata0-master UDMA100
acd0: DVDROM <LITEON DVD-ROM LTD-165H> at ata0-slave UDMA33
$

The LED is still on. The devices are jumpered properly in master-slave 
terms. I'll try to get a hold of another cable and see if splitting them 
across cables helps. Thanks a lot.
