should two Promise FastTrak TX2000 cards work in a single machine?

I've been using a FreeBSD 4.8 machine that had a boot disk on a
single Promise FastTrak Ultra133 tx2 controller, and a mirrored
pair raid for user data on a Promise FastTrak TX2000.
These are 80GB drives.

The boot disk died so I decided to buy another TX2000, a pair of
disks for /.  These are 40GB drives.

I expect to see
ar0: composed of 2 40GB drives, with /
ar1: composed to 2 80GB drives, with /home

If the machine has a single TX2000 FreeBSD works fine;
with both TX2000s each with a pair of disks FreeBSD gets confused.

I've seen:

- ar0 identified as an 80GB raid, but each disk is a 40GB drive
(it's somehow mixing the data from each)

- during boot the 40GB pair listed as mirror 1, the 80GB pair listed as
mirror 2, but ar0 composed of the 80GB drives.  kernel panics
because it can't find init.

Same behavior with 4.9.

Both cards are using the latest firmware.

Thanks in advance for any advice,
