The Oktapussy drivers on Aminet should work just fine with the 2008 - that's what I have in my 4000. They usually create not an "oktagon.device", though, but a "2nd.scsi.device" and a "SoftSCSI_OktagonC9XEA.device" or something (check the resident libraries with Sysinfo, or Ranger or something). HDToolbox will usually pick it up too.
I don't remember ever having problems with re-enabling the ROM though. Tried reseating the card? Sounds like a hardware error....
