Well, it works on Windows, so it might just need some workaround
if the timings are the issue here.

I will try to give it a go under Linux this weekend, to see if this is a
XFree86 or a OS issue.

I have no problem with that, but both my drives are UDMA100 only
(Seagate Barracuda and a slightly sick IBM DTLA). What version of
FreeBSD are you running? Have you tried doing

atacontrol mode 0 udma133 udma133

or:

atacontrol mode 0 udma100 udma100

but you have to have a recent system to have atacontrol (-STABLE, i think?)
Try to post your dmesg to see what the problem is.

Regards,

Gabriel

ps - And do you have any audio problems, btw?
