atapicam error messages at boot/appears to work nonetheless

[Matthias Andree]

I'm getting complaints from ata or atapicam during boot-up, but my
CD-ROM seems fine (reading, at least). ACPI enabled, sym driver enabled
+ in use with a 875 chip (Tekram DC-390F) and cd0, da0, sa0, sa1.

Is this something to worry about?
