Ok, here's the dmesg output using the hpt366 old IDE driver,
2.6.21-rc7, SMP: 

[  160.926355] HPT302: IDE controller at PCI slot 0000:03:06.0

Which looks ok to me I guess.  It found my MD disks on there and
assmebled them, eventually.  *grin*

I'll reboot and send out the corresponding ATA HPT37x driver dmesg...
