I was using v2 - but there shouldn't be any code changes between v3 and v2....so I hadn't re-based.

I'm working in the fixes branch from pdx86.git (with the aim of making it easier for Hans to pull in the patches). It's possible I've goofed somehow...though not sure how :(

I'll go double check - but likely won't be until tomorrow I'm afraid. I should probably just wait for the patch to be accepted and then work from there....
