RAID card confusing mptable?

I've got an American Megatrends Titan III PCI EISA Pentium motherboard
from around 1996.  I have two Pentium 166MHz processors (P54C) on it.
I recently bought a brand new Promise FastTrak S150 TX2plus RAID
controller and a couple of parallel ATA hard drives to go with it.

I installed i386 FreeBSD-CURRENT 5.2.1 generic.
If I did not configure any RAID arrays through the hardware BIOS on the
controller card, the card was detected and the system would start.
If I configured a RAID array in the hardware, the system would always
reboot while probing the hardware.

I wanted to be able to use the RAID capabilities of the card, and I
thought an update might help, so I updated to the latest code I could get
and rebuilt the world and the kernel, using the latest GENERIC
configuration.  This was yesterday 4/18, and I finished the process today

I have the same problem, except that instead of a reboot when I have a
RAID array configured, I get an error message during the mptable_probe:
"Panic: mptable_walk_table: Unknown MP Config Entry 18
at line 401 in file /usr/src/sys/i386/i386/mptable.c"

For comparison, if RAID is not configured on the card, the system boots,
but during the mptable_probe I get an
"MP Config Table has bad signature: \^B"
Then later when it gets around to detecting the RAID card, I see this:
atapci1: <Promise PDC20371 SATA150 controller> port
0xee80-0xeebf mem 0xffac0000-0xffadffff,0xffaff000-0xffafffff irq 9 at
device 11
.0 on pci0
atapci1: failed: rid 0x20 is memory, requested 4
atapci1: Reserved 0x20000 bytes for rid 0x20 type 3 at 0xffac0000
atapci1: Reserved 0x1000 bytes for rid 0x1c type 3 at 0xffaff000

Running the mptable utility after the system has started doesn't yield any
unusual results or the mysterious \^B signature.

I've tried booting with and without ACPI, but there's no difference.
Can anyone give me any troubleshooting advice?  I am still very new to
