You can only install 64 bit guest OSes on a 64 bit host OS running on a 64 bit CPU... if there's a 32 bit anything in that chain... no 64 bit guest :-)

Nope, VirtualBox's 64-bit guest support is decided by whether your processor supports Intel VT-x (or AMD-V) extensions only. 64-bit guests work fine on a 32-bit OS running on a processor with virtualization extensions.
Errr.. right... I should have known that. :-P I stand corrected... again. Ha. AMD-V is on almost all AMD processors except a few low end (eg Semperon). From what I've read this morning, VT-x isn't on all intel... in fact it's quite a confusing mess... http://arstechnica.com/microsoft/news/2009/05/r2e-microsoft-intel-goof-up-wi... and http://www.zdnet.com/blog/bott/how-many-intel-cpus-will-fail-the-xp-mode-tes... and http://en.wikipedia.org/wiki/X86_virtualization#Intel_Virtualization_Technol... give some info on it.
