Would you consider having a small partition to do the same for HEAD? :P

Well it's hard to test stuff out without the hardware. :) And it's
quite possible a lot of silly looking issues are actually working
around real bugs in the hardware.

I'm glad this issue was solved so quickly for you. Let's hope we can
get you onto testing out HEAD (in a separate partition!) so we can
ensure we don't break the basic stuff. :)
