Thanks for trying it out. I just waved this in front of Søren.

The apparently new mis-detection issue is certainly something to be 
concerned about. You're absolutely sure it was detected as a Marvell 
reliably (with rr232x still in there) before you applied that patch?

The fact that the patch didn't do anything to solve your Marvell 
controller problem is too bad, also, but the mis-detection issue is of 
more immediate concern since this HT1000/Marvell-fixing code is being 
vetted for inclusion in 7.0-R.

Have you tried that hardware combination with any other OSes to see if 
it's a FreeBSD-specific issue and not just a hardware-level issue?

I haven't had a chance to confirm myself since my box with the Marvell 
controller in it is a long drive away from me, but Søren did get his 
PCI-X 8-port Marvell working perfectly fine after making these fixes.
