Don't know about the other issues, but I have a Dell with similar 
Intel components, and it did the same SATA thing when I put a new 
drive in it yesterday:

atapci1: <Intel ICH7 SATA300 controller> port 
0xfe00-0xfe07,0xfe10-0xfe13,0xfe20-0xfe27,0xfe30-0xfe33,0xfea0-0xfeaf 
irq 20 at device 31.2 on pci0
ad4: 76293MB <Maxtor 6L080M0 BACE1G10> at ata2-master SATA150
ad6: 305245MB <Seagate ST3320620AS 3.AAK> at ata3-master SATA150

The ad6 drive is supposed to do SATA-300, but realistically, other 
bottlenecks dictate it's not going to get anywhere near the '150 
speed, so I'm not terribly worried about it.  cp'ing a 4GB file to 
/dev/null yielded 57MB/sec.
