Hmmm kernel possibly, hardware doubtful - I do not have any troubles 
like this when using the Passport under Windoz... This problem occurred 
on several different Linux systems all running the same version of 
openSuse 11.2.. I don't want to get heavily involved in trying to run 
tests however, got too many other projects in the fire, so I don't want 
to reinstall Wine rc7 again.. Just want to report I had an issue and am 
willing to submit a bug report..

One way I can sometimes recreate the dismount problem, is to 
"accidentally" disconnect the USB drive while it is mounted. Linux can 
get confused about it when I then reconnect the drive, but not always, 
sometimes Linux does recover gracefully by killing off any apps that 
were using the drive at the time of the disconnect. Sometimes however, 
Linux fails to recover and then the drive becomes unable to be 
dismounted.  (this scenario happens once in awhile to me, easy to pull 
the USB chord out of the USB socket, but it was NOT a factor when I 
tried to use wine rc7 and got the previously mentioned failures) But I 
am not sure that this particular issue is of interest to the wine 
developers...
