There are 486SX upgrades for 286 chips available.  Hard to find, but available.

The only ones I know about were for 286 to 486 and then only the square chips.

Do you know if these where for any accelerator card with a 286 chip? Also is it possible to upgrade it even more? 586?

You may be right on that.  I'll have to check when I get home from work.  Do know the manufacturer CLAIMED it was a 486.  However, like you pointed out, the Cyrix was just a souped up 386.

Still, it'd be better than a kick in the head!

I don't think that 486SX can be used on 286 based motherboard. I think it is the 486SLC produced by Cyrix that was an upgraded 386SX (witch has an external 16bit bus to be used on 286 based boards). The 486SX is a 486DX without math processor.

Got around to checking the 286 to 486.  It's a  TI486SLC, so we're looking at a 486 in 386 clothing.
