OK, a re-diffed version of that patch against 3.5 works. (For the
record, it looks like it's against a newer version of the file than is
included in 3.5, and also it seems to have spaces in place of tabs - not
sure if that's a problem on your end or on mine). So that looks good to
me, assuming none of the stuff on the Launchpad bug is a roadblock.
Thanks! One small nit: it's just the 'Vaio Z', not 'Vaio TT Z'. 'Vaio
TT' is a separate (rather older) system; there's no such thing as a 'TT
Z', to my knowledge. You might want to say 'some Vaio Zs', or something
like that, since there have been several generations of the Z, some of
which this won't apply to...
