Boots successfully with UniBeast USB but not latest Chimera?

[crunky404]

Same build as in my profile - H77 DS3H and ATI HD 6450 graphics.

Since I installed ML, I have only been able to successfully boot using the UniBeast 1.5.1 flash drive I created.
I've reinstalled latest Chimera from MultiBeast 4.6.1 several times, but no matter what it always hangs on

macx_swapon SUCCESS

and doesn't go anywhere no matter how long I leave it there.
I use a GBU321 bluetooth adapter for my Magic Trackpad; if I leave it attached I see a few messages about connecting to the trackpad after this but never anything else.

I can't really find much useful information about OS X hanging at macx_swapon SUCCESS, so I'm not really sure where to go from here.
I'd just be like to be able to get my Chimera to boot correctly!

when I install Chimera from MultiBeast it will run in textmode instead of graphical mode (like when you start from UniBeast USB). i also notice that my LAN light keeps blinking while stuck on macx_swapon SUCCESS. perhaps a network error?

edit: i noticed when booting from the USB drive it still hangs in the same area before finishing booting, but when booting from UniBeast USB it loads Atheros ethernet driver, gives MAC address, gives another message about power management before booting into OS X. i didn't think I would need to install Atheros drivers from Multibeast because it works under OS X, but I'm going to give it a shot...

edit2: after installing AtherosL1cEthernet, it picks up the MAC address after macx_swapon SUCCESS, but still hangs there, meanwhile orange LAN LED keeps blinking..
