I don't mean this in either a bad or saracstic way whatsoever, but more 
in the spirit of "give it a shot and see what happens"......so.........
Give it a shot and see what happens.
You won't lose anything by taking that approach, if the RAID controller 
is *not* recognized you won't be able to commence an installation.
Write your data to CD/DVD first, then "go for it"
Honestly, I can't think of a method more certain to verify whether or 
not your RAID controller is supported.

While you're at it, go for 5.3-RELEASE...why stop at the earlier 
version? There *is* mention (of course) of the Promise RAID controller 
at:
http://www.freebsd.org/releases/5.3R/relnotes-i386.html#PROC
and it looks sorta hopeful for you.

and I quote;
[snip]
The ata(4) driver now supports cardbus(4) ATA/SATA controllers.

A number of bugs in the ata(4) driver have been fixed. Most notably, 
master/slave device detection should work better, and some problems with 
timeouts should be resolved.

The ata(4) driver now supports the Promise command sequencer present on 
all modern Promise controllers (PDC203** PDC206**).

     Note: This also adds preliminary support for the Promise SX4/SX4000 
as a ``normal'' Promise ATA controller; ATA RAID's are supported, but 
only RAID0, RAID1, and RAID0+1
[/snip]

Good luck! and do please let us know if you were successful or not.

Regards,
-Colin
