I second what Thomas says. Try not going quite so close to the 2Gb limit and use smaller partitions. I believe NSDPatch.cfg under OS3.5+ has a line for the IVS controller to recognize drives >4Gb. I'd try a small 100mb partition, install 2.0 and take it from there. Maybe later upgrade to 3.1 rom or softkick to 3.1 and then install 3.5, 3.9 etc.
