With due respect to all, most matters do not usually occur overnight, though some do!
In our building there is absolutely no concern or interest from the majority of owners that are not on the Committee until the AGM. If you are an owner and interested could you not follow the EC Meetings and or Minutes? SM should supply on request if you do not have access to. Our Committee on occassion gets an email from our SM a week or so before they send out the AGM Notice asking for items to add to the agenda, Bugger all notice for us either, but at least we are taking the time to be involved throughout the year so most items are not a surprise. I don't think there is a requirement to ask all owners for additions before writing agenda.
Having said that, I would still bring up my concerns at the meeting, what have you got to lose? The chair could shut you up or not! 
Struggler, are you sure you cannot attend this meeting? Sounds like you should.
Cheers,
CBF
