I should think so, though it does carry the risk of updating a kernel as 
per usual, with a sick little twist. You will have to update your kernel 
extensions to 64-bit as well, otherwise these will just not work. If you 
can build a 64-bit toolchain in a native 64-bit environment (with 64-bit 
userland as well) and export it, you might find life easier during 
transition. A lot of the userland stuff that did run in 32-bit you might 
find no longer works in the new kernelspace. I do know from upgrading a 
Debian box (from Knoppix 6.1) that qt and Firefox break with some 
interesting errors.
