Sparc servers worked with such a model (64bit kernel, 32bit userspace) for years, why x86-64 must be different.
The situation is completely different between SPARC and SPARC64 than x86 and x86_64: There everything is twice as big, and only the need for more than 4GiB of memory space can force 64 bits. AMD learned from this mistake (and Itanium, and also from Pentium Pro's abysmal performance on then-current 16 bit code) and x86_64 programs are almost as dense as x86.
