* Staple a romtag to ODFS
* Add resulting file to release + adf

* SCSI ATA PASSTHROUGH: enforce word alignment of scsi_Data
* TD_GETGEOMETRY: enforce word alignment of io_Data, check for NULL pointer and check io_Length
* NSCMD_DEVICEQUERY: Check for NULL pointer and alignment of io_Data

Don't constantly allocate/deallocate memory
