>Description:
Some variants of the Viking Interworks 256MB Compact Flash cards doesn't work,
it is not recognized as a disk. The disc-controller is detected but no disk.
The problem variant returns the code 0x8400 in the configuration word. FreeBSD
looks for the magic words 0x844a or 0x848a (in sys/dev/ata/ata-disk.c, function
ad_probe).
The attached patch also looks for the 0x8400 magic word.
