Intel ICH5 on FreeBSD 5.1

[freebsd]

Im trying to get an Intel-based box to boot on a FreeBSD 5.1 kernel (generic) yet I seem to be having issues doing this.  I am using a SATA drive and frankly, Im unable to find anything on google.  Here's the output from dmesg for the SATA device:

atapci1: <Intel ICH5 SATA150 controller> port 0xdc00-0xdc0f,0xe000-0xe003,0xe400-0xe407,0xe800-0xe803,0xec00-0xec07 irq 11 at device 31.2 on pci0

the drive:
ad4: 76319MB <ST380013AS> [155061/16/63] at ata2-master UDMA33


Is there anything special that I need to add to a GENERIC kernel for this box to be able to run a generic kernel?  I've given it a couple of tries and none of them work.  Fails to mount root.  Any suggestions and/or pointers are more than welcome.  On a reply, please make sure to CC me as I am not currently on this mailing list.  Thank you.
