ral (Cnet CWP-854) wireless hostap + dhcpd - what is the obvious bit I am missing?

Seeing that in 3.7, wireless support had come to include the really
cheap ralink based cards, I thought I'd ran out of excuses and bought me
a couple.  I was a bit worried when I noticed too late (ie after I'd
ordered the cards from a web shop) that ral(4) cards require PCI 2.2.
Then again I never got around to figuring out how to nail which PCI
revision a system uses, and it does not seem to have anything to do with
whatever is stopping the setup from working (the card gets recognized
and appears to be sending signals).

Anyway, one ral went into the box my wife insists needs to run microsoft,
and one went into the gateway as that machine's third network interface.
The other two are 

xl0 - facing an ADSL router, with our sole official and fixed address,
      hostname.xl0 says

      inet NONE

xl1 - facing the wired home network, hostname xl1 says

      inet NONE

no surprises, obviously I do NAT between the two. It has Just Worked for
quite a while, and this part still does.

Adding to this we now have ral0, with hostname.ral0 which now says

up media DS11 mediaopt hostap nwid kakemonster nwkey 0x1deadbeef1

(the DS11 part is there because a laptop I tend to use has that mode as
its top speeed, and I started out with a two internal subnets - for wireless and for wired - but
switched to a bridged config which sounded reasonable after reading
http://marc.theaimsgroup.com/?l=openbsd-pf&m=104788096126953&w=2.  No
noticeable difference I'm afraid other than a noticeable delay while
network deamons start and for the login parts of ssh connections)

I thought DHCP would be useful (and since I've never needed to set up 
a dhcpd before, this may be where the problem lies), and arrived at this

default-lease-time 600;
max-lease-time 7200;


shared-network BSDLY {

# Ethernet Network
subnet netmask {
    option  domain-name "bsdly.net";
    option  routers;
    option domain-name-servers,,,,;

host dellheim {
    hardware ethernet 00:08:A1:85:8D:86;

host amidala {
    hardware ethernet 00:03:0d:12:49:d7;

It works, sort of - sshing in to the gateway via the wired net and doing
a "dhclient ral0" gets an answer from the dhcpd listening on ral0, and
apparently an address gets assigned.  However, on the intended clients
coming from the wireless, the effects are not quite what I wanted - the
kakemonster network announces itself, but never actually assigns an IP
address to the client.

At the moment, ifconfig says

peter_(_at_)_skapet:~$ ifconfig

now if you've read this far, I'm grateful even if you did not notice
anything obvious :)

But as usual I'm fairly convinced that there's something silly like a
typo or something other truly trivial that's tripping me up here.

And since you're probably wondering, there seems to be a generous
handful of wide open wireless networks withing range.  I won't need to
impose too much on my neighbors, I hope.
