I can definitely notice a large speed boost in 64 bit - mostly when compiling but also system responsiveness. Though that could be because I've been on AMD for the last two (and only two self-built) computers I've had.

Remember, AMD64 is an extension to the IA32 instruction set, it's not as if it's a completely new instruction set (such as IA64).
Personally I've never had any issues running 32-Bit operating systems on either AMD or Intel 64-Bit capable CPUs (although I understand some of the early 64-Bit Pentium 4's might have a few bugs due to Intel cutting corners).
I have had issues on Windows though trying to get 64-Bit codecs.
Speed wise, I haven't noticed a difference between 32-Bit and 64-Bit, if anything 64-Bit Ubuntu was more memory hungry.
