[ltp] hibernate, X220, memory, ubuntu Maverick, and ssd

Dear all,

I am running Ubuntu 10.10 on a Thinkpad x220 (mechanical hd if that 
matters). It works great, except a few things like it does not go to 
hibernation. I have a message "cannot suspend" when I close the lid, or 
when I try to hibernate.
It shuts down and reboots cleanly.
I wonder why. I read somewhere that the swap partition must be at least 
as large as the amount of main memory. Is this the reason why? 
Otherwise, any idea?

Now, an other question: I just received an SSD disk to replace the 
mechanical one. I do not have any experience with SSDs. I wonder whether 
fs check matters with them, and if yes, about their frequency (currently 
I check my hd every 100 boots).

Thanks for any help/comment,
