How do I... (PWM)

I'm out of VPs on my Javelin, and I need to add 1 (or maybe 2) additional PWM outputs. (What I'd actually like to do is move all my existing PWM work to dedicated chips, and use the VPs for other things.)
So Ideally I'd like a chip that will take serial input from the Javelin (ie, commands) and give me, say,·8 channels of PWM output. Something like a PWMPAL, except I'd very much prefer not to deal with PWMPAL's dedicated pin assignments and limit of 4 PWMs. And I'd like the serial link to be fast (I need to fade lights across several dimmer channels simultaneously and quickly, which is going to mean sending a lot of commands!)
Suggestions?

You can program an SX28 with 8 pwm channels and 2 uarts quite
easily.
