FreeBSD tanaka 7.0-CURRENT FreeBSD 7.0-CURRENT #4: Sun Jul 22 12:54:36 PDT 2007 root at tanaka:/usr/obj/usr/src/sys/TANAKA i386
>Description:
	The controller is detected, but the disks themselves are not. The disks are reported in the BIOS.

	The motherboard is an ASUS P4S800D-X. 

[root at tanaka ~]# dmesg | grep -i sata
atapci1: <SiS 180 SATA150 controller> port 0xeff0-0xeff7,0xefe4-0xefe7,0xefa8-0xefaf,0xefe0-0xefe3,0xef90-0xef9f irq 17 at device 5.0 on pci0
[root at tanaka ~]# atacontrol list

    Slave:       no device present
ATA channel 3:
    Master:      no device present
    Slave:       no device present

	I checked to see if this was a regression from kern/87585, but it doesn't appear to be (I compared the code in ata_sis_init or whatever under ata-control.c to the supplied patch and it seemed the same).
