Why is "SAMSUNG CD-ROM SC-148F" blacklisted?

The "SAMSUNG CD-ROM SC-148F" drive is listed in drive_blacklist in
ide-dma.c. However, this drive worked well with DMA enabled with earlier
kernel versions (<=2.6.8.1) where the "via82cxxx" driver did not look at
this blacklist. So the question: what was the reason for blacklisting this
(apparently working) drive? Is it still valid?

Details on my CD-ROM drive are pasted below.
