Dual AMD64, APCI woes, 5.2.1-Rel, Help!

I'm trying to get another FreeBSD system up at our office for a mission critical app. Unfortunately if I can't figure this problem out, FreeBSD will be tossed and Linux used instead and I really don't want that. We've always been a FreeBSD/i386 house, this is our first foray into Opteron. Here's the particulars....

Rhapsody HDAMA-F mainboard
Dual bge 10/100/1000 nics
8gb ram
dual Opteron 2.0ghz cpus
LSI megaraid amr 320-2X raid controller w/128mb cache
Four ultra-320 15Krpm scsi drives, 35gb each

The drives are set up raid 10. A striped set of 70gb, then a 70gb mirror.

I'm using the amd64 ISO for 5.2.1-Release

My problem seems to center around APCI. If I disable APCI in the bios and boot off the install CD and select the boot without APCI, the system comes up and installs just fine. However, it seems to only recognize one cpu. At least, the sysctl variables I looked at appeared to indicate just one cpu and the top display didn't have a cpu column.

If I leave APCI enabled, the system boots off the cd fine but when the installed starts to probe the devices, it gets stuck just after the line for the CD drive (acd0). I am pretty certain that that is exactly the point where it's probing the scsi drives, because if APCI is turned off - right after the acd0 probe is where geom starts and the disk is recognized. The lsi controller is definitely recognized ok further up in the probe display.

I'd just disable APCI to get around this, but if FreeBSD will only use one cpu.... management will switch to Suse (which purportedly runs this configuration perfectly) and I'd really like to stay FreeBSD. Normally I'd just love to dive into the new and unknown (to me) opteron/5.X/APCI stuff. But I'm completely out of time on this project to get the machine up. Could anyone possibly offer me some quick pointers or help on this? I've googled lots and so far not come up with anything concrete, other than "disable APCI" which seems to leave me with just one cpu.
