Yes, I'm now working on the 2.x series.

Yes, we have improved the P5 code in 2.004, and it should be faster than
the current (3.04) cyberian client, on a P5. On a PP200 / NT4 the 2.004
P5 code runs at ~263 kkeys/s and the cyberian client runs at ~245
kkeys/s (iddle machine at night, cheking real blocks).
The cyberian P6 code is currently faster than ours, but we will have a
faster P6 core in 2.005 (*don't ask me 'when').

I've tried to improve both the 6x86 code and the K5 code in 2.004, and
it should be faster than my old v1-based code. I just checked the client
speed page and it seems that 2.004 is checking ~280 kkeys/s under Linux.
