FreeBSD and SATA Port Multipliers

I have a system running FreeBSD 8.0-RC1 that contains 3x Sil3124 PCI-E
SATA controller cards. Each card has 3x Sil3726 Port Multipliers
attached (5 slots per SATA PM). The problem is that the disks are often
not all detected by FreeBSD, even though the controller Option ROMs list
all of the installed physical disks. Which drive(s) are not detected
seems to vary with each boot. All of the port multipliers are detected
every boot, it's just the drives which aren't getting probed.
I've tried the following patch,
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/129784 , which may have
helped - it picks up 6-8 out of 9 disks, but obviously that's not
ideal. The motherboard BIOS version is current, as is the firmware for
the SATA controllers.
Does anyone have any ideas or other patches that I may try?
Thanks,
Steve Polyack
