long standing atapicam problem (kern/78929)

Hello,

I'm hunted by ODD problems for quiet some time now. It seems it still is 
the same problem mentioned in 
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/78929 4 years ago.
I have exactly the same problems with today's -current. But since ICH8 
and newer don't have ATA channels any more, I can't connect the drive to 
anything else than my onboard JMB363.
Unfortunately I don't have the knowledge to solve it myself :(
But I could help testing :)
And I'd need atapicam for VirtualBox

Best regards,

-Harry
