Dual booting 64-bit and 32-bit kernels

[A J Stiles <deb64@earthshod.co.uk>]

If I partition my drive appropriately, can I use LILO to dual-boot a 32-bit 
kernel and a 64-bit kernel with  {at least}  a shared /home and swap space, 
but separate / partitions?

I think it should be possible, this way, to keep all the nasty binary-only 
stuff tucked out of the way in a directory which won't even appear when the 
system is booted in 64-bit mode.

But I thought I'd ask first, incase someone knows of a good reason I have not 
thought of why this won't work.
