I announced my intention to work on rtld side of TLS support some time
ago and I already have some work in progress.

Interested parties can easily compile GCC 3.3 port with TLS support.
Run 'make patch' in the ports directory and then edit
work/gcc-3.3/gcc/configure to look for binutils 2.13 instead of 2.14
while testing for the platform TLS support. Compile and install the
port.
