so, I managed to set up dual (well, trial-) boot, with Linux, Windows & MacOS
but, it seems I couldn't get the Cameleon bootleader to get installed on the SSD. so I can only boot MacOS if I put the UniBeast USB stick in the laptop. then the SSD-installed MacOS would only boot with the '-x' option (would hang at boot otherwise)
when booted, WiFi doesn't work, but other things seem to work. this is after trying to install drivers using the latest MultBeast for Mavericks
interestingly while Linux's grub does recognize the MacOS partition, it's can't boot into it
I thought this information is useful for other people, hence reporting
