Wow, that update to BETA4 did the trick! While running SCHED_4BSD:

root@nudel olivleh1> dd if=/dev/zero of=/mnt/files/test.dd bs=64k count=32000
32000+0 records in
32000+0 records out
2097152000 bytes transferred in 27.161129 secs (77211518 bytes/sec)

with SCHED_ULE:
root@nudel olivleh1> dd if=/dev/zero of=/mnt/files/test.dd bs=64k count=32000
32000+0 records in
32000+0 records out
2097152000 bytes transferred in 27.004929 secs (77658119 bytes/sec)
