I want to add that I've been using Aros on a laptop and a netbook for a while now, and both are running in VESA mode. It's perfectly responsive, and while a native chipset driver would probably be better, most people would never notice the difference. It's 24/32bit, full resolution, waaay faster than AGA, games work fine on it, so it's not a turn-off for me to use VESA at all.
I'd suggest installing Aros and just running in VESA mode for a while until the native drivers are written, and in the mean time you still get to try out this cool, free OS.
