Try to boot a 64-bit kernel there. Either download a LFS LiveCD (even 
the x86 version - the 64-bit kernel is named "linux64" there), or follow 
the initial binutils and gcc instructions in CLFS. The resulting gcc is 
able to cross-compile a 64-bit kernel (make ARCH=x86_64 
CROSS_COMPILE=x86_64-unknown-linux-gnu- menuconfig && make ARCH=x86_64 
CROSS_COMPILE=x86_64-unknown-linux-gnu-).

And if you don't want to download anything big and/or waste the CPU 
time, here is a pre-made 64-bit kernel that, however, doesn't support 
your hardware without initramfs:

Just add it to GRUB menu.
