I moved this discussion to a separate thread.

In the meanwhile the following primes were found
233*2^1700734-1 by Cruelty, July 2010
13*2^2606075-1 by Curtis, December 2011
13*2^2642943-1 by Curtis, February 2012

Therefore, there are now only three k<300 which largest known prime has less than 300k binary bits:
k=191 at n=240802, tested up to n=4.2M
k=249 at n=251036, tested up to n=1.1M
k=151 at n=263895, tested up to n=2.9M

All other k<300 have largest known primes with more than 300k bits.
