I think you haven't understood the impact of AMD64/x86-64 extensions.
There is a small set of architectural enhancements which were also
introduced, which lead to small performance increasements. But apart
from that, all you basically get is the extension of address space. (So
for applications with a large memory footprint (we're speaking >4GB),
that may indeed help.)

The performance impact is minimal. But I indeed believe it's quite
unfortunate having to revert to 32bit applications and libs on a 64bit
OS.
