Issues with 1.33b1 / Realtelk devices / Watchguard x series

Aloha,

Just tried to upgrade one of my watchguards which I'd moved to m0n0wall 
a while back ; the new beta version doesn't seem to support my network 
cards anymore.  They're definitely realtek cards, I can't recall the 
model number at the moment,as I've just wiped out my fw ;-)

Anyways, here's the rather limited info I can provide currently:

After an initial reboot, everything was down and not responding.  Hook 
up console (which was also unfun!), the version has updated and also 
it's kept the config:

     LAN IP address: 10.11.12.225

     Port configuration:

     LAN   -> re1
     WAN   -> re0
     OPT1  -> re2 (Wireless LAN)
     OPT2  -> re3 (HomePlug LAN)
     OPT3  -> re4 (OPT3)
     OPT4  -> re5 (OPT4)

Trying to ping stuff on various segments fails, so 'reset to factory 
defaults' and lo and behold my interfaces have disappeared :-(

Has the recent upgrade to the realtek driver gone awry somehow ?
