Yes, umass over ehci works for me
(this is a RELENG_5 installation from yesterday):

FreeBSD 5.3-STABLE #1: Wed Nov 10 05:27:51 CET 2004

ehci_idone: need toggle update status=80028d40 nstatus=80008c80
umass0: ARCHOS ARCHOS USB2.0 (P4a), rev 2.00/11.01, addr 2
ehci_idone: need toggle update status=80028d40 nstatus=80008c80
da2 at umass-sim0 bus 0 target 0 lun 0
da2: <HITACHI_ DK23DA-20 00J2> Fixed Direct Access SCSI-0 device 
da2: 1.000MB/s transfers
da2: 19077MB (39070080 512 byte sectors: 255H 63S/T 2432C)

$ dd if=/dev/zero of=xxx 
156237824 bytes transferred in 32.482556 secs (4809899 bytes/sec)


.. this is an Archos mp3 player with a 20G harddisk and an USB 2.0 interface, 
though with a FAT filesystem, not NTFS.
