Opteron in 32 vs. 64 bit

When I looked at the specification of Opteron (some time ago), it
seemed that one had to use 64 bit code in order to get the advantage
of extra working registers (a significant shortage on 32 bit X86). Is
this still true, or has it been revised?

Its my understanding that you can only use the extra registers in 64 bit mode on the released opteron.
