32bit Encryption on 64bit Core2Duo

Not sure which section this fits most appropriately but, I am planning on setting up my system with a 64bit kernel, and using dm-crypt to encrypt root and swap, using aes_x86_64 or serpent.

I am confused with regards to the hardware compatibility mode:

1) will running 32 bit software in compatibility mode affect the operation of the 64 bit software?

"...Using the AES_x86_64 "AMD64 users only":
as of kernel-2.6.9 the 64 bit version of the AES cipher that can be used in replacement of the 32 bit AES cipher that's used by default. you must load this module before running the cryptsetup command or else the 32bit AES will be use instead. type "modprobe aes_x86_64" and continue with creation of mappings. "

2)If the system is setup and formatted with the aes module (the only one available on the live cd) rather than aes_x86_64 can I still change to aes_x86_64 after install?
