A bit of Googling turned up this <http://vsegost.com/Catalog/96/9658.shtml>
with scanned GIFs of ГОСТ Р34.10-1994. There is a link to the other one,
ГОСТ Р34.10-2001 on that page as well. This does seem to document
the parameters.

Is the real problem the lack of English language documentation?
If so, I'm sure that the people who would like to use these algorithms
could arrange for translations of the two documents, and perhaps even
make that an individual submission as an Internet draft.

That may be explained by its use in card payment systems. As you may
know if you follow the news, a Cambridge team has just found a HUGE hole
in the UK's chip and pin payment system, but a subtext of that announcement
is that other weaknesses documented in previous years still have not been fixed.
Signature algorithms used in payment systems get embedded in all kinds
of devices, and software systems, making it hard to deprecate stuff fast.
