Wouldn't surprise me really, from what I remember, a lot of the driver 
code was kludgey at best. I might have to pull out some of those old 
drives over the holidays and see what the current driver code looks like. 
Its been awhile since I did any kernel hacking anyway.

Speaking of which, I unearthed an odd one myself a few weeks ago while 
sorting out drives. It is a external Hitachi drive with a special 
interface card. I never did manage to get it working under Linux or 
FreeBSD (no driver or docs). I'm not sure which box the card is in right 
now, but I did locate the drive again. Its built like a tank and unless 
I'm mistaken, its a single speed drive.
