I moved this discussion to a separate thread.
In the meanwhile the following primes were found
233*2^17007341 by Cruelty, July 2010
13*2^26060751 by Curtis, December 2011
13*2^26429431 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.
