thanks for the info! google now tells me that Michael Stephen Hanni wrote the +0x80000 hack for running ct65550 on his powerbook 3400 :) Currently theres a a lot of possibiliites as to what could be going wrong, so knowing whats right's a good place to start :) I'll try and get a well formed patch in when i get this all working (and I *will* get it working... *grr* ;)) noticed i forgot to mention the immediate symtoms in my last post - the driver starts up, the server gets to running, but there's no display, no change in output whatsover... We're running an fbdev driver for the card in the kernel, could i be seeing some sort of resorce allocation problem? We currently run an fbdev based driver in Xfree86 that works flawlessly but leaves a lot to be desired on the accelaration side, so hardware is all good.
