I guess it may be drive dependent then. Here is the relevant part of
the logs for my "superfloppy". (Matsushita-Kotobuki LKM-F334-105)

ata2.01 is the ide floppy drive, as the slave, and ata2.00 is the
CD-ROM, as master. Both are on the secondary IDE controller. When I
have time to play with it again, I will see if limiting the DMA mode
on the drive will help. I don't know enough about the new drivers to
know if it will make a difference. I also need to boot FC6 on this
machine to capture how it identifies the drive... (I have to get
more information so I can file a bug report...)
