At the Berlin C++ committee meeting earlier this month the LWG decided 
expressed interest in getting a further proposal for infinite precision 
arithmetic for TR2 based on 
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1718.pdf

Maarten Kronenburg is now working on putting together a further proposal for 
the standards committee. I asked him a few days ago if he was interested in 
submitting his reference implementation to Boost, and he replied that his 
underlying computational functions are written in X86 assembler.

Thus for Boost a portable C++ implementation would be needed, switching over 
to the assembler version for supported platforms. You might want to email 
Maarten to see if he would like help with a portable C++ version and with 
getting a proposal ready for Boost submission.
