The HP-2133 (C7-M/CN896) did not fail yesterday.
Find a C7-M/CX700 machine.

You might hook the rss feed at:
http://forum.netbookuser.com/viewforum.php?id=8
where my rants/raves/speculations are logged and
the other people helping me test make their comments.

In particular:

The original instructions (including download url):
http://forum.netbookuser.com/viewtopic.php?pid=6702#p6702

Updated installation instructions:
http://forum.netbookuser.com/viewtopic.php?id=907 

Also ignore anything you read in LKML that I have been doing
this in secret - those authors just never got the memo. ;)
