I've been working on something:
http://ubuntuforums.org/showpost.php?p=10562947&postcount=31
However, don't just jump into that yet! Specifically, in your case, I see you had to use the "acpi_osi=force" boot parameter (possibly to deal with a fan/cooling issue) so I need to add some warnings about such things :)
You'd be doing me a huge favor if you'd post the output of the Boot Info Script as described here:
http://bootinfoscript.sourceforge.net/
I'm also trying to figure out the effects of BURG on this whole thing which means I have to break my own stuff and fix it a few times :D
I personally detest BURG, IMHO it's just a kludge!
Hi Kansasnoob thank you for your continuing interest in this bizarre problem. As requested I have added the results.txt file.

I hope this makes sense to you! It surpasses my knowledge by many lightyears!
p.s. As to the "acpi_osi=force" thing. I set this variable after reading many posts from Linuxers with problematic Toshiba's AS A PRECAUTION, I'm no longer convinced I really need it. By coincidence I had already gone back to acpi_osi=off and my laptop behaves just fine. Temperature and fan behaviour have not been an issue with this laptop sofar (keep your fingers crossed).
