If it wont work under Windows, wont work in Wine ;).

I've successfully updated firmware on a Yamaha SCSI CDR under Wine 
(and Wine is very useful for figuring out what windows SCSI apps do - 
you can get it to log all SCSI CDBs which are sent).

I sent similar to Yamaha years ago and got the source for their DOS 
firmware programme back, which allowed me to adapt some existing SCSI 
code (the original globalfilesystem.org's seagate disk firmware 
upgrade programme) to flash the drive. It broke with later, bigger, 
firmware which needed a slightly different procedure for updating 
firmware - at which point Yamaha had moved to a win32 app for 
firmware upgrade, hence I used Wine.

If ATAPI on Windows is implemented via SCSI, or else if the Wine 
ATAPI layer is similar to the Wine SCSI layer, then you should try 
get Wine to dump the conversation of the application for future 
reference (even a native Linux app).
