Does OpenBSD's wpa_supplicant support PSK?

[Zbigniew]

Hi! I'm unable to access my WiFi router. The problem is, that every
attempt to register by using wpa_supplicant is refused:

My /etc/wpa_supplicant.conf:

#v+
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
ap_scan=0
network={
        ssid="MY-SSID"
        scan_ssid=1
        key_mgmt=WPA-PSK
        psk=*VERY-LONG-STRING*
}
#v-

(of course, there isn't literally *VERY-LONG-STRING* there)

My hostname.rum0:

#v+
wpa
dhclient
#v-

(from what I see, most probably "wpa" line is ignored)

It's not a problem with flawed network description; I successfully
tested it on Linux, FreeBSD and NetBSD. Actually, all the three were
quite pleased with even shorter version, like this:

#v+
network={
        ssid="MY-SSID"
        psk=*VERY-LONG-STRING*
}
#v-

I made attempts using Linksys and Atheros USB-dongles - but it doesn't
seem to be hardware dependent; in both cases it failed to log into my
WiFi-point. Looks like probably psk-sequence is passed with errors?

I noticed one more thing: Linksys dongle was during boot-up - with
wpa_supplicant inactive - trying to register at my neighbour's WiFi
access point (most probably he's using some other authentication
scheme), of course, it wasn't successful - no Internet connection -
but dhclient was able to obtain IP address from his local network.

Anyway, I'm interested in connecting to my own access point, that's
why I'm asking: does OpenBSD's wpa_supplicant need some "special
treatment" - or it doesn't support authentication using PSK-string at
all?

One more question: assuming, that with a little help I'll make it
work, I'll need it to make it run _before_ the system reads
/etc/hostname.rum0, where there is dhclient invocation; so how can I
execute /etc/rc.d/wpa_supplicant _earlier_ during system boot-up
sequence?

Thanks in advance for every helpful tip.
