installing 5.4 on RAID1 using Promise TX2200

I just got an Promise TX2200 "RAID" Controller and 2x250GB SATA
Drives for my new webserver.
As soon as I define a raid of some sort, the installation cd just
reboots the system. I think that happens at the stage where the
kernel should be loaded.
I've used the TX2000 with IDE drives before. There I had similar
problems. I learned that the BIOS on the controller should not be
used to define the array.
What I did back then:
- do not define the array with the Controller BIOS
- boot from the install cd, start the live-filesystem
- use atacontrol to define the array
- install freebsd to the new ar0 device (I'm not sure anymore if
that device just turned up or I had to reboot first)
- everything works fine
This doesn't seem to work with the TX2200 anymore. I can define the
mirror from the live-filesystem, but the ar0 device does not turn up.
Once I try boot from the installation cd again, I end up in the
endless reboot cycle.
The default FreeBSD kernel can handle the controller though. If
install freebsd on a seperate harddisk, there are no problems
utilizing the mirrored disks with atacontrol. The system boots
normally. I can format and mount the filesystem, recover from
removing one of the disks etc.
Does the installation CD use a different kernel than a default system?
I tried installing using /stand/systinstall (after booting the other
installation on the seperate hd). But I could not get it to install
correctly. It would just overwrite the existing installation...
