Dear Hostilian,
Many thanks for you're tutorial, finally after 5 hours i managed to get my broken upgrade from 6.1 to 6.2 up and running again!!
Tried several how-to/ guides. None of them worked with a combi of passthrough sata disks and vmware workstation with a bridged network adapter.
When I tried you're approach it worked flawlessly!
Thanks
Greetz

PS edit: the step of first adding the disks as scsi is crucial, after the first boot to the dsm install page, shutdown the vm, and remove the disks and re-add them as sata disks!
