Got xfree86 running nicely on the IA-1. After comparing jailbait's xf86config with the 4.0.1 versions, I finally figured out what was needed. The Cyberblade chip is apparently a trident variant and works nicely with that driver. A bit slow but definately works. (Gnome surplanting wince - life is good).
Still struggling to figure out what's going on with Scream and running it on my laptop (kde). Something happening with artsd and madplay. I suspect artsd has changed quite a bit in how it does its process handling and doesn't like my code for scream's console io/processes when spawned by artsdsp. Still works fine with iPAQ (typical ;-)
