Adsense and overture on the same site (not page)

Can I do this?

Basically, I want to have a firefox referrel on the front page of my site. My site has "firefox" in the domain name (registered years before mozilla was founded) and it does VERY nicely on the firefox referrels.

On the rest of the site, I'd like to use overture. It would not be on the same site as the firefox referrel button. I'm stripping adsense off my site; the referrel button's worth too much to risk getting banned by a click attack or something similar. I've had a warning from google about invalid clicks yesterday so this is a real issue.

If it's not allowed, I'll just run the rest of the site without ads until the day that google cancels the referrel program, then go to adsense sitewide. (The latter option actually makes a kind of sense ... the site may develop traffic faster without ads.)

Correction, the overture ads would not be on the same PAGE as the firefox referrel button. I'd have trhe referrel button on the front page and overture everywhere else on the site.
