Ask the flist: Second Life low-graphics?

My lappy is feeling its age and the latest Windlight incarnations of Second Life are causing it to grouse about having an under-spec graphics card.  Waily waily, poor little me, I know.  Question is, are there any l33t h@x for optimising Second Life for low-end graphics stuff, or is it just a case of playing with the sliders? 

It's been done for mobiles, so surely there's some market in producing an alternate skinny browser that doesn't have all the upgrade-your-graphics-card-richboy visual richness and trades it off for decent framerate?  I'd take a quarter of the Z-depth and cell shading over real lighting, really.  Actually, I'd always take cell shading because I have a hardon for cell shading (Google Sketchup, thou makest me go squee).
