Apparently not all Promise controllers are/were affected. I've been
running CURRENT since Pawel committed ZFS with an onboard Promise:

atapci0: <Promise PDC20319 SATA150 controller> port
0xb000-0xb03f,0xb400-0xb40f,0xb800-0xb87f mem
0xfc024000-0xfc024fff,0xfc000000-0xfc01ffff irq 23 at device 4.0 on
pci4
ar0: 305245MB <Promise Fasttrak RAID0 (stripe 64 KB)> status: READY
ar1: 305245MB <Promise Fasttrak RAID0 (stripe 64 KB)> status: READY

atapci0_at_pci0:4:4:0:     class=0x010400 card=0x80f51043 chip=0x3319105a
rev=0x02 hdr=0x00
    vendor     = 'Promise Technology Inc'
    device     = 'PDC20319(??) FastTrak SATA150 TX4 Controller'
    class      = mass storage
    subclass   = RAID

The only problem I have and I'm filling a pr for that, is when booting
from CD with the controller enabled, the BTX loader just reboots.
