Comment 8 for bug 645311

I've implemented some patches to fix this, which you can find in this git branch on gitorious:
http://meego.gitorious.org/~pmaydell/qemu-maemo/pmaydell-qemu-meego/commits/nand-prefetch

and submitted a merge request to upstream:
http://meego.gitorious.org/qemu-maemo/qemu/merge_requests/1

Some notes if you're testing with the Ubuntu image:
(1) you'll need to dd some extra space onto the end of the .img file, otherwise the filesystem can't be resized and lots of things will complain about having no disk space:
dd if=/dev/zero of=ubuntu-netbook-10.10-preinstalled-netbook-armel+omap.img oflag=append conv=notrunc bs=1048576 count=1024

(2) it's pretty slow in places (minutes!), especially initial filesystem resize and setting up swap

(3) I was able to get the image to do the initial boot and setup, then it did its automated reboot, and then failed to start X because python died with a glibc-detected double free or something similar. I haven't investigated this, but the NAND access is pretty clearly working so I think that's a separate issue.
