I worked on building the phablet for the nook. I stopped because all reports were it works very badly with only 500 mb ram. Hashcode has ported it to the kindle fire and found he could only open a couple apps before it froze up. However, he did good work on porting and put the changes on github at https://github.com/KFire-Android . You can look for phablet branches on the otter branches. The kernel changes are also present in some of his repos. Look around those repos for good hints on getting started.The kindle fire is also an omap processor, albeit omap4, so it is close to ours. The changes should be similar.
