In the Bay Area, VCs expect and want the founder/CEO to make approximately $150K to $175K per year after the VC round (i.e. Seies A). I have confirmed this by asking VC panels here in Orange County during open-mike sessions.
What should be clearly understood is that you are actually financing a part of that compensation via your significant equity dilution that would result from the new vesting schedule put in place by the VC! You typically can't escape this new vesting if you want VC money...which is why PG's question about how much cash will you take to just walk away from it has real substance behind it.
