Experiencing a kernel panic w/a NULL pointer being dereferenced on modprobe of the byo-switcheroo module, following your issue #3 suggestions. Used the 9231be9 commit on a Gentoo Linux box, vanilla kernel 3.0.1. Used a modded version of asus-switcheroo ebuild so that it would get the latest git commit, and install byo-switcheroo. Hardware is a Asus UL30JT, which reportedly works with the -VT info.

Please provide dmesg (netconsole is a convenient way to do that on these systems)

From my Syslog, since the kernel oops doesn't completely kill my laptop. Three separate instances:
