Please add to Ezra (or in an additional Samuel2 type) 750MHz and if cache amount is emulated/has an effect, then also 600/650/667/700/733MHz and 300/400/533MHz (like Eden/EBGA Samuel2).

Nehemiah is also missing:

• 1333MHz (Socket370) and 533/667/733/800 (Eden/EBGA) CPUs
• 200MHz FSB EBGA/CN400 chipset variants for 1000/1200/1300/1400MHz CPUs

• Cyrix III currently present is actually Cyrix III (Samuel), while Cyrix III (Joshua) isn't emulated at all. Would be interesting to see it since it supports both Cyrix EMMI and 3DNow!.
• Pentium III Tualatin - if cache amount has an effect - do you have the 512KB models? Same for Pentium Pro 512KB/1MB models?
• Am5x86 4x50MHz - can this overclock setting be selected somehow?

Edit: it seems cache emulation is not applicable
