I'm doing exactly that with 2.6.10-rc3. umount does take a very long time (but I had just written 600Mb+ over usb 1.1)
Are you sure it doesn't come back if you leave it long enough?
Do the throughput sums; you'll be suprised how long it takes to send more than a few Mb over usb 1.1 (1.5Mb/s). Eg 600Mb = 7minutes
Usb 2 should be much faster; Do you have EHCI loaded?
