I was planning on picking up a Pismo this weekend. It's a 400MHz. I was reading up on it to find that the ATI Rage chip in it supports up to 16MB of VRAM(?). So my idea is to find tha same type of memory, desolder the 8MB and solder on a few new chips to be 16MB. Would this work, or would I need to do some poking around in OF?
