FreeBSD 5.3 and Adaptec RaidUtils

Between 5.2.1 and 5.3-RC2 the rasr device was removed:

In FreeBSD 5.2.1 it use to be that using the compat4x port and
creating a symlink of /dev/rasr0 to /dev/rdpti17 would be enough to
allow Adaptec's RAID management binaries work. However, that trick no
longer appears to be working. When you run Adaptec's raidutil (either
from the port or from the Adaptec package itself) the symlink
disappears and raidutil returns an error stating that it couldn't
connect to /dev/rdptr17.

Any ideas on why the symlink disappears or another way to get the old
Adaptec binaries to work under FreeBSD 5.3 short of rewriting asr.c to
include a device alias?
